Implements compatibility checking for initializers in procedure pointer declarations. This work exposed some inconsistency in how ELEMENTAL interfaces were handled and checked, from both unrestricted intrinsic functions and others, and some refinements needed for function result compatbility checking; these have also been ironed out. Some new warnings are now emitted, and this affected a dozen or so tests. Differential Revision: https://reviews.llvm.org/D159026
