SIL: Move description of abstraction patterns to AbstractionPattern.h and write new comment in SILGenPoly describing function thunks, NFC Probably SILGenPoly.cpp should be named SILGenThunk.cpp, but I'm saving that for if I ever extract the duplication between bridging thunks and re-abstraction thunks.
