Implement a simple cache in headersearch. This speeds up
...
preprocessing 483.xalancbmk by about 10%, reducing the number
of file lookup queries from 2139411 to 199466 (over 10x)

Finally bite the bullet and make the major change: split the clang namespace
...
out of the llvm namespace. This makes the clang namespace be a sibling of
llvm instead of being a child.
The good thing about this is that it makes many things unambiguous. The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier. IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

Wean LookupSubframeworkHeader off std::strings, use the new SmallString

class instead. SmallString allows to code to avoid hitting malloc in
the normal case (or will, when some other stuff is converted over).
