patch: using llvm::sys::path in FileManager

Hi Doug,

Please review the FileManager refactoring patch I promised
(Issue 4175044: refactors FileManager to use llvm::sys::path instead of hand-rolled code. - Code Review or the attachment). It depends
on the is_separator patch I sent to you and llvmdev. Thanks!

Much cleaner, thanks!
