Driver: Quote the command in crash reproduction scripts.

This fixes crash report generation when filenames have spaces. It also
removes an awkward workaround that quoted *some* arguments when
generating crash reports.

Treat -g1 as -gline-tables-only

-g1 on gcc (and also IBM's xlc) are documented to be very similar to
-gline-tables-only. Our -gline-tables-only might still be more verbose than -g1
on other compilers, but currently we treat -g1 as -g, and so we're producing
much more debug info at -g1 than everybody else. Treating -g1 as
-gline-tables-only brings us much closer to what everyone else is doing.

Follow-up commit to r211657 which introduced these macros, but not for MSVC. This turns out to break our freestanding tests on Windows when compiling in MSVC-compatible mode. It was decided (http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20141020/116942.html is the start of the thread) to support this as part of Clang's interface on all platforms.

[modules] Initial support for explicitly loading .pcm files.

Implicit module builds are not well-suited to a lot of build systems. In
particular, they fare badly in distributed build systems, and they lead to
build artifacts that are not tracked as part of the usual dependency management
process. This change allows explicitly-built module files (which are already
supported through the -emit-module flag) to be explicitly loaded into a build,
allowing build systems to opt to manage module builds and dependencies
themselves.

This is only the first step in supporting such configurations, and it should
be considered experimental and subject to change or removal for now.

Driver: rename Windows to MSVCToolChain

This renames the Windows toolchain to MSVCToolChain.  This is a preparatory step

Support using sample profiles with partial debug info (driver)

Summary:
When using a profile, we used to require the use -gmlt so that we could
get access to the line locations. This is used to match line numbers in
the input profile to the line numbers in the function's IR.

But this is actually not necessary. The driver can provide source
location tracking without the emission of debug information. In these
cases, the annotation 'llvm.dbg.cu' is missing from the IR, but the
actual line location annotations are still present.

This patch tells the driver to only emit source location tracking
when -fprofile-sample-use is present in the command line.

This eliminates some i8* GEPs and makes the IR that clang emits a bit

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.
