cc51dc649a Add Swift enumerator value for CodeView::SourceLanguage
Summary:
Swift now generates PDBs for debugging on Windows. llvm and lldb
need a language enumerator value too properly handle the output
emitted by swiftc.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

7999b4fa48 [PDB] Refactor the PDB symbol classes to fix a reuse bug.
The way DIA SDK works is that when you request a symbol, it
gets assigned an internal identifier that is unique for the
life of the session.  You can then use this identifier to
get back the same symbol, with all of the same internal state
that it had before, even if you "destroyed" the original
copy of the object you had.

This didn't work properly in our native implementation, and
if you destroyed an object for a particular symbol, then
requested the same symbol again, it would get assigned a new
ID and you'd get a fresh copy of the object.  In order to fix
this some refactoring had to happen to properly reuse cached
objects.  Some unittests are added to verify that symbol
reuse is taking place, making use of the new unittest input
feature.

da61120749 [PDB] Add a method to get the full path of the source file for PDBSymbolCompiland
Summary:
Redefine PDBSymbolCompiland::getSourceFileName() to return the filename (w/o directory) of the source file that is used to compile the compiland. This is because the result returned previously is ambiguous. It could be the filename, relative path or full path of the source file. 

Move the implementation of SymbolFilePDB::GetSourceFileNameForPDBCompiland() into a new method PDBSymbolCompiland::getSourceFileFullPath().

1b1a70f172 General usability improvements to generic PDB library.
1. Added some asserts to make sure concrete symbol types don't
   get constructed with RawSymbols that have an incompatible
   SymTag enum value.
2. Added new forwarding macros that auto-define an Id/Sym method
   pair whenever there is a method that returns a SymIndexId.
   Previously we would just provide one method that returned only
   the SymIndexId and it was up to the caller to use the Session
   object to get a pointer to the symbol.  Now we automatically
   get both the method that returns the Id, as well as a method
   that returns the pointer directly with just one macro.
3. Added some methods for dumping straight to stdout that can
   be used from inside the debugger for diagnostics during a
   debug session.
4. Added a clone() method and a cast<T>() method to PDBSymbol
   that can shorten some usage patterns.

9a818ad193 [llvm-pdbdump] Rewrite dumper using visitor pattern.
This increases the flexibility of how to dump different
symbol types -- necessary for context-sensitive formatting of
symbol types -- and also improves the modularity by allowing
the dumping to be implemented in the actual dumper, as opposed
to in the PDB library.

a952c49c20 llvm-pdbdump: Add more comprehensive dumping of symbol types.
In particular this patch adds the ability to dump complete
function signature information including argument types as
correctly formatted strings.  A side effect of this is that
almost all symbol and meta types are now formatted.

c074de041b Add concrete type overloads to PDBSymbol::findChildren().
Frequently you only want to iterate over children of a specific
type (e.g. functions).  Previously you would get back a generic
interface that allowed iteration over the base symbol type,
which you would have to dyn_cast<> each one of.  With this patch,
we allow the user to specify the concrete type as a template
parameter, and it will return an iterator which returns instances
of the concrete type directly.

a5549178f1 Rewrite llvm-pdbdump in terms of LLVMDebugInfoPDB.
This makes llvm-pdbdump available on all platforms, although it
will currently fail to create a dumper if there is no PDB reader
implementation for the current platform.

It implements dumping of compilands and children, which is less
information than was previously available, but it has to be
rewritten from scratch using the new set of interfaces, so the
rest of the functionality will be added back in subsequent commits.

bae16b3f53 DebugInfoPDB: Make the symbol base case hold an IPDBSession ref.
Dumping a symbol often requires access to data that isn't inside
the symbol hierarchy, but which is only accessible through the
top-level session.  This patch is a pure interface change to give
symbols a reference to the session.

21473f7bb6 Some cleanup for libpdb.
This patch implements a few of the optional suggestions from the
initial patch comitting libpdb.  In particular, it implements a
virtual function out of line for each of the concrete classes.

A few other minor cleanups exist as well, such as using override
instead of virtual, etc.
