>> Hi - the attached patch provides implementations and tests for sys::fs::can_read() and sys::fs::can_write() for Unix.  These were adapted from the previous implementations in lib/Support/Unix/Path.inc.  can_execute() could be implemented quite similarly, but I wasn't sure where the best place to add a test for it would be, so left it out for now.

I'm surprised that anything in LLVM and clang is actually using canWrite().
It appears that there is one use, in clang, and that one looks pretty
suspicious. Perhaps it can be removed altogether instead of ported to PathV2?
