Benjamin Kramer dce83c522c Avoid initializing posix_spawn_file_actions_t if not used. 
- glibc falls back to fork+exec if a file actions object is present.
- On BSDs this saves a malloc.

Douglas Gregor 56b2ffdaba Rip out realpath() support. It's expensive, and often a bad idea, and 
I have another way to achieve the same goal.

Cameron Zwarich f73f5ba21c Attempt to fix the build after r125228.

Douglas Gregor 529329e859 Add llvm::sys::path::canonical(), which provides the canonicalized 
name of a path, after resolving symbolic links and eliminating excess
path elements such as "foo/../" and "./".

This routine still needs a Windows implementation, but I don't have a
Windows machine available. Help? Please?
