MS ABI: Emit more canonical vbptr stores and loads

This eliminates some i8* GEPs and makes the IR that clang emits a bit
more canonical. More work is needed for vftables, but that isn't a clear
win so I plan to send it for review.

Reland r219810 "Fix late template parsing leak with incremental processing"

Original message:
Add a second late template parser callback meant to cleanup any
resources allocated by late template parsing.  Call it from the
Sema::ActOnEndOfTranslationUnit method after all pending template
instantiations have been completed.  Teach Parser::ParseTopLevelDecl to
install the cleanup callback when incremental processing is enabled so
that Parser::TemplateIds can be freed.

SanitizerBlacklist: Use spelling location for blacklisting purposes.

When SanitizerBlacklist decides if the SourceLocation is blacklisted,
we need to first turn it into a SpellingLoc before fetching the filename
and scanning "src:" entries. Otherwise we will fail to fecth the
correct filename for function definitions coming from macro expansion.

Fixup for r220403: Use getFileLoc() instead of getSpellingLoc() in SanitizerBlacklist.

This also handles the case where function name (not its body)
is obtained from macro expansion.

DebugInfo: Omit scopes in -gmlt to reduce metadata size (on disk and in memory)

I haven't done any actual impact analysis of this change as it's a
strict improvement, but I'd be curious to know how much it helps.

Correct importing of the type of a TemplateArgument

It's not clear how this would be tested - I imagine we should have an
ASTImporter test that RAVs the new AST and checks that all the elements
in it are from this ASTContext and not the foreign one... but I know
little about the ASTImporter and how/where that testing might be done.

Resubmit "Improve Windows toolchain support for non-standard environments."

This resubmits change r220226.  That change broke the chromium
build bots because chromium it ships an hermetic MSVC toolchain
that it expects clang to fallback to by finding it on the path.

This patch fixes the issue by bumping up the prioritization of PATH
when looking for MSVC binaries.

Make a good guess about where MSVC and Windows SDK libraries are for linking.

When a user has not configured a standard Visual Studio environment
by running vcvarsall, clang tries its best to find Visual Studio
include files and executables anyway.  This patch makes clang also
try to find system and Windows SDK libraries for linking against,
as well.

This allows a module to specify that it logically contains a file, but that
said file is non-modular and intended for textual inclusion. This allows
layering checks to work properly in the presence of such files.
