some cases where functions with no language linkage were being treated as having
C language linkage. In particular, don't warn in

extern "C" {
  static NonPod foo();
}

Since getLanguageLinkage checks the language linkage, the linkage computation
cannot use the language linkage. Break the loop by checking just the context
in the linkage computation.

instantiation in order to permit devirtualization later in codegen, skip over
pure functions since those can't be devirtualization targets.

It's possible (e.g. after an LTO build) that an internal global may be used for
debugging purposes. If that's the case appending a '.b' to it makes it hard to
find that variable. Steal the name from the old GV before deleting it so that
they can find that variable again.

Parse objective C information as efficiently as possible and without taking dangerous runtime locks.

Reworked the way objective C information is parsed by:
1 - don't read all class names up front, this is about 500K of data with names
2 - add a 32 bit hash map that maps a hash of a name to the Class pointer (isa)
3 - Improved name lookups by using the new hash map
4 - split up reading the objc runtime info into dynamic and shared cache since the shared cache only needs to be read once.
5 - When reading all isa values, also get the 32 bit hash instead of the name
6 - Read names lazily now that we don't need all names up front
7 - Allow the hash maps to not be there and still have this function correctly

There is dead code in here with all of the various methods I tried. I want to check this in first to not lose any of it in case we need to revert to any of the extra code. I will promptly cleanup and commit again.
