Don't try to generate common globals for C++ files, instead of depending on the FE to set NoCommon, and simplify CodeGenOptions initialization.

Put CompilerInvocation testing code in clang-cc instead of clang for now, I can't bear to link all of clang into 'clang' yet. :)

stat a file but where mmaping it fails.  In this case, we emit an
error like:

This will fix the selfhost buildbots but will 'break' the others (sigh) because
they're still linked against older LLVM which is emitting less optimized IR.

was being added to the Result vector, but not being put in the
cache.  This means that if the cache was reused wholesale for a
later query that it would be missing this entry and we'd do an
incorrect load elimination.

Unfortunately, it's not really possible to write a useful 
testcase for this, but this unbreaks 255.vortex.

Kill off clang/win32 which contains the hand generated Visual Studio project files. These files are severely out of date and have been superseded by the CMake build system. RIP.

Don't call Decl::CollectingStats(false) and Stmt::CollectingStats(false). When called with false these functions return whether statistics are enabled. They don't change any state. Since we're not using the return value avoid calling them in the first place.
