+  bool UseGCC47;

...

+  llvm::sys::fs::exists("/usr/lib/gcc47", UseGCC47);

UseGCC47 can be used uninitialized. From the code I guess you can use
the simpler ]

UseGCC47 = llvm::sys::fs::exists("/usr/lib/gcc47");

The patch has grown quite a bit no? Can you split it? For example,
just gcc47 bits, the hash-style bits, etc.
