Diego Novillo 795f53ba64 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.

Preprocessor 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. 2014-10-21 19:24:06 +00:00
