[llvm-commits] [PATCH] Bugpoint/Support: Fix llvm::FindExecutable not looking for files ending with .exe

[NAKAMURA Takumi]

Michael,

An refined patch is attached. Please take a look.
Confirmed on mingw, mingw-cross, f12 and centos5.

  - get rid of extra sys::Path variable FoundPath
  - suppose value of FindProgramByName() must be valid when it is not empty
