Where is sys::fs::canonicalize()?

Hi,

as the subject says, I was just wondering where the implementation of
sys::fs::canonicalize() might be. The function is declared in
llvm/Support/FileSystem.h, but I couldn't find its implementation
within lib/Support. Consequently, any application using this function
doesn't link. Am I missing something here?

Regards,

Looks like it got implemented, then reverted due to buildbot breakage,
and never re-committed:

Ok, looks like it doesn't do what I expected anyway. I thought it would also
resolve symbolic links within paths on UNIX systems and simplify .. and .
components. I don't really care about capitalisation...

ciao,
Mario
