74a3868dbb This patch adds a new Clang compiler flag "-gline-tables-only". 
It reduces the amount of emitted debug information:
1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram,
DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only.
2) .debug_str contains only function names.
3) No debug data for types/namespaces/variables is emitted.
4) The data in .debug_line is enough to produce valid stack traces with
function names and line numbers.

2d7c57ec1d Remove the ref/value inconsistency in filter_decl_iterator. 
filter_decl_iterator had a weird mismatch where both op* and op-> returned T*
making it difficult to generalize this filtering behavior into a reusable
library of any kind.

This change errs on the side of value, making op-> return T* and op* return
T&.

b7e821a6aa Change location information for synthesized properties to be at the 
property file/line rather than the @synthesize file/line. Avoids
some nasty confusing-ness with conflating the file from the scope
and the line from the original declaration. Use    the current scope
location as a separate parameter so that we can    match it up
better in the line table with the beginning of the scope.

Update a couple of testcases accordingly since I had to change
that we actually use the passed in location in EmitFunctionStart
and for the new metadata parameter and add a new testcase to
make sure we've got the right line numbers for synthesized
properties.

4c006e557d Reapply r150631: 
"Add a completed/incomplete type difference. This allows us to have
    partial types for contexts and forward decls while allowing us to
    complete types later on for debug purposes.

    This piggy-backs on the metadata replacement and rauw changes
    for temporary nodes and takes advantage of the incremental
    support I added in earlier. This allows us to, if we decide,
    to limit adding methods and variables to structures in order
    to limit the amount of debug information output into a .o file.

    The caching is a bit complicated though so any thoughts on
    untangling that are welcome."

with a fix:

 - Remove all RAUW during type construction by adding stub versions
   of types that we later complete.

and some TODOs:

 - Add an RAUW cache for forward declared types so that we can replace
   them at the end of compilation.
 - Remove the code that updates on completed types because we no
   longer need to have that happen. We emit incomplete types on
   purpose and only want to know when we want to complete them.

This seems to negatively affect compile time onsome ObjC tests
(which use a lot of partial diagnostics I assume). I have to come
up with a way to keep them inline without including Diagnostic.h
everywhere. Now adding a new diagnostic requires a full rebuild
of e.g. the static analyzer which doesn't even use those diagnostics.

dafff94759 constexpr irgen: Add irgen support for APValue::Struct, APValue::Union, 
APValue::Array and APValue::MemberPointer. All APValue values can now be emitted
as constants.

Add new CGCXXABI entry point for emitting an APValue MemberPointer. The other
entrypoints dealing with constant member pointers are no longer necessary and
will be removed in a later change.

Switch codegen from using EvaluateAsRValue/EvaluateAsLValue to
VarDecl::evaluateValue. This performs caching and deals with the nasty cases in
C++11 where a non-const object's initializer can refer indirectly to
previously-initialized fields within the same object.

Building the intermediate APValue object incurs a measurable performance hit on
pathological testcases with huge initializer lists, so we continue to build IR
directly from the Expr nodes for array and record types outside of C++11.

dc9166c8e1 Keep track of all declarations of an Objective-C class (both forward 
declarations and definitions) as ObjCInterfaceDecls within the same
redeclaration chain. This new representation matches what we do for
C/C++ variables/functions/classes/templates/etc., and makes it
possible to answer the query "where are all of the declarations of
this class?"

b8c3aaf479 Allow getting all source locations of selector identifiers in a ObjCMethodDecl. 
Instead of always storing all source locations for the selector identifiers
we check whether all the identifiers are in a "standard" position; "standard" position is

  -Immediately before the arguments: -(id)first:(int)x second:(int)y;
  -With a space between the arguments: -(id)first: (int)x second: (int)y;
  -For nullary selectors, immediately before ';': -(void)release;

In such cases we infer the locations instead of storing them.

351762cda2 A few more tweaks to the blocks AST representation: 
- BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

717d9b0e2f It's kindof silly that ExtQuals has an ASTContext&, and we can use that 
space better.  Remove this reference.  To make that work, change some APIs
(most importantly, getDesugaredType()) to take an ASTContext& if they
need to return a QualType.  Simultaneously, diminish the need to return a
QualType by introducing some useful APIs on SplitQualType, which is
just a std::pair<const Type *, Qualifiers>.

8b07ec253d Substantially alter the design of the Objective C type AST by introducing 
ObjCObjectType, which is basically just a pair of
  one of {primitive-id, primitive-Class, user-defined @class}
with
  a list of protocols.
An ObjCObjectPointerType is therefore just a pointer which always points to
one of these types (possibly sugared).  ObjCInterfaceType is now just a kind
of ObjCObjectType which happens to not carry any protocols.

Alter a rather large number of use sites to use ObjCObjectType instead of
ObjCInterfaceType.  Store an ObjCInterfaceType as a pointer on the decl rather
than hashing them in a FoldingSet.  Remove some number of methods that are no
longer used, at least after this patch.

By simplifying ObjCObjectPointerType, we are now able to easily remove and apply
pointers to Objective-C types, which is crucial for a certain kind of ObjC++
metaprogramming common in WebKit.

2408e32096 Make the InjectedClassNameType the canonical type of the current instantiation 
of a class template or class template partial specialization.  That is to
say, in
  template <class T> class A { ... };
or
  template <class T> class B<const T*> { ... };
make 'A<T>' and 'B<const T*>' sugar for the corresponding InjectedClassNameType
when written inside the appropriate context.  This allows us to track the
current instantiation appropriately even inside AST routines.  It also allows
us to compute a DeclContext for a type much more efficiently, at some extra
cost every time we write a template specialization (which can be optimized,
but I've left it simple in this patch).

7ec5043c2c Change CodeGenModule to rely on the Module's symbol table instead of 
shadowing it in the GlobalDeclMap.  Eliminates the string-uniquing
requirement for mangled names, which should help C++ codegen times a little.
Forces us to do string lookups instead of pointer lookups, which might hurt
codegen times a little across the board.  We'll see how it plays out.

Removing the string-uniquing requirement implicitly fixes any bugs like
PR6635 which arose from the fact that we had multiple uniquing tables for
different kinds of identifiers.

e78aac41de Create a new InjectedClassNameType to represent bare-word references to the 
injected class name of a class template or class template partial specialization.
This is a non-canonical type;  the canonical type is still a template 
specialization type.  This becomes the TypeForDecl of the pattern declaration,
which cleans up some amount of code (and complicates some other parts, but
whatever).

Fixes PR6326 and probably a few others, primarily by re-establishing a few
invariants about TypeLoc sizes.
