Old fork of llvm-mirror, used on older RPCS3 builds

Zachary Turner ad31712bf4 Add llvm::sys::fs::real_path.
LLVM already has real_path like functionality, but it is
cumbersome to use and involves clean up after (e.g. you have
to call openFileForRead, then close the resulting FD).

Furthermore, on Windows it doesn't work for directories since
opening a directory and opening a file require slightly
different flags.

So I add a simple function `real_path` which works for all
paths on all platforms and has a simple to use interface.

In doing so, I add the ability to opt in to resolving tilde
expressions (e.g. ~/foo), which are normally handled by
the shell.
