[PATCH] D33258: clang-cl: Fix path-based MSVC version detection

[Reid Kleckner via Phabricator via cfe-commits]

rnk added a comment.

I'd rather not hardcode all the msvc archs. IMO we should just look up one level and check if that's called bin, and continue if so. I think I had:

  bool IsBin = llvm::sys::path::filename(PathEntry).compare_lower("bin");
  if (!IsBin) {
    PathEntry = llvm::sys::path::parent_path(PathEntry);
    IsBin = llvm::sys::path::filename(TestPath).compare_lower("bin");
  }
  if (IsBin) {
    ...

The compare_lower is also a fix, because my path looks like ".../VC/Bin".
