<rdar://problem/13210494>
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. llvm-svn: 175101
