method names and to replace some method names
with more descriptive names (e.g., "getLeft()"
instead of "Left()").  No real functionality
change.

This doesn't quite work yet because the calls to treeDecrement and treeIncrement
operate at the leaf level, not on pathNode(Level) as required.

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.

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.

Add a FD member to FileEntry which isn't used but will be shortly.

 - Default argument expressions pick up the value kind of the incoming
   expression, not the value kind of the parameter it initializes.
 - When building a template argument for substitution, A::x is an rvalue
   if x is an instance method.
 - Anonymous struct/union paths pick up value kind the same way that
   normal member accesses do;  extract out a common code path for this.

Enable the value-kind assertion, now that it passes self-host.
