The final result of all this refactoring: instead of doing stat immediately
...
followed by an open for every source file we open, probe the file system with
'open' and then do an fstat when it succeeds. open+fstat is faster than
stat+open because the kernel only has to perform the string->inode mapping
once. Presumably it gets faster the deeper in your filesystem a lookup
happens.
For -Eonly on cocoa.h, this reduces system time from 0.042s to 0.039s on
my machine, a 7.7% speedup.

change the 'is directory' indicator to be a null-or-not
...
pointer that is passed down through the APIs, and make
FileSystemStatCache::get be the one that filters out
directory lookups that hit files. This also paves the
way to have stat queries be able to return opened files.
