9d2872db74 [OpenCL] Add generic AS to 'this' pointer
Address spaces are cast into generic before invoking the constructor.

Added support for a trailing Qualifiers object in FunctionProtoType.

Note: This recommits the previously reverted patch, 
      but now it is commited together with a fix for lldb.

5cdc2cda28 [AST] Store "UsesADL" information in CallExpr.
Summary:
Currently the Clang AST doesn't store information about how the callee of a CallExpr was found. Specifically if it was found using ADL.

However, this information is invaluable to tooling. Consider a tool which renames usages of a function. If the originally CallExpr was formed using ADL, then the tooling may need to additionally qualify the replacement.
Without information about how the callee was found, the tooling is left scratching it's head. Additionally, we want to be able to match ADL calls as quickly as possible, which means avoiding computing the answer on the fly.

This patch changes `CallExpr` to store whether it's callee was found using ADL. It does not change the size of any AST nodes.

2413638a6d NFC: Rename TemplateDecl dump utilities
There is a clang::TemplateDecl AST type, so a method called
VisitTemplateDecl looks like it should 'override' the method from the

Only store the needed data in IfStmt. This cuts the size of IfStmt

The result of this is that for the common case of an

instead of 8 bytes + 5 pointers + 2 SourceLocation.

c457766c6d Consistently create a new declaration when merging a pre-existing but
hidden definition with a would-be-parsed redefinition.

This permits a bunch of cleanups. In particular, we no longer need to
take merged definitions into account when checking declaration
visibility, only when checking definition visibility, which makes
certain visibility checks take linear instead of quadratic time.

We could also now remove the UPD_DECL_EXPORTED update record and track
on each declaration whether it was demoted from a definition (as we
already do for variables), but I'm not doing that in this patch to keep
the changes here simpler.

12216f1d4a [AST] Sink 'part of explicit cast' down into ImplicitCastExpr
Summary:
As discussed in IRC with @rsmith, it is slightly not good to keep that in the `CastExpr` itself:
Given the explicit cast, which is represented in AST as an `ExplicitCastExpr` + `ImplicitCastExpr`'s,
only the  `ImplicitCastExpr`'s will be marked as `PartOfExplicitCast`, but not the `ExplicitCastExpr` itself.
Thus, it is only ever `true` for `ImplicitCastExpr`'s, so we don't need to write/read/dump it for `ExplicitCastExpr`'s.

We don't need to worry that we write the `PartOfExplicitCast` in PCH after `CastExpr::path_iterator`,
since the `ExprImplicitCastAbbrev` is only used when the `NumBaseSpecs == 0`, i.e. there is no 'path'.

d55661db3c [Sema] Mark implicitly-inserted ICE's as being part of explicit cast (PR38166)
Summary:
As discussed in [[ https://bugs.llvm.org/show_bug.cgi?id=38166 | PR38166 ]], we need to be able to distinqush whether the cast
we are visiting is actually a cast, or part of an `ExplicitCast`.
There are at least four ways to get there:
1. Introduce a new `CastKind`, and use it instead of `IntegralCast` if we are in `ExplicitCast`.

   Would work, but does not scale - what if we will need more of these cast kinds?
2. Introduce a flag in `CastExprBits`, whether this cast is part of `ExplicitCast` or not.

   Would work, but it isn't immediately clear where it needs to be set.
2. Fix `ScalarExprEmitter::VisitCastExpr()` to visit these `NoOp` casts.

   As pointed out by @rsmith, CodeGenFunction::EmitMaterializeTemporaryExpr calls

   skipRValueSubobjectAdjustments, which steps over the CK_NoOp cast`,

   which explains why we currently don't visit those.

   This is probably impossible, as @efriedma points out, that is intentional as per `[class.temporary]` in the standard
3. And the simplest one, just record which NoOp casts we skip.

   It just kinda works as-is afterwards.

But, the approach with a flag is the least intrusive one, and is probably the best one overall.

091b1efafb Ensure code complete with !LoadExternal sees all local decls.
Summary:
noload_lookups() was too lazy: in addition to avoiding external decls, it
avoided populating the lazy lookup structure for internal decls.
This is the right behavior for the existing callsite in ASTDumper, but I think
it's not a very useful default, so we populate it by default.

While here:
 - remove an unused test file accidentally added in r322371.
 - remove lookups_begin()/lookups_end() in favor of lookups().begin(), which is
   more common and more efficient.
