Detailed Description
class llvm::StringMap< ValueTy, AllocatorTy >
StringMap - This is an unconventional map that is specialized for handling keys that are "strings", which are basically ranges of bytes.
This does some funky memory allocation and hashing things to make it extremely efficient, storing the string data after the value in the map.
