[SIL] Move GenFunc to use getBuiltinInfo and getIntrinsicInfo.

Browse Source 
Make the functions support a wider range of builtins and store types to make
it possible.

This is an optimization - the cached ID will be used for builtin identification,
instead of retrieval of the string name and using it as the key.
