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.

the result code of the stat to/from the PCH file since it is always 0.
