expmed.c (mode_for_extraction): New function.
* expmed.c (mode_for_extraction): New function.
(store_bit_field, extract_bit_field): Use it.
* expr.h: Prototype it and provide an enum for its first argument.
* combine.c, function.c, recog.c: Don't include insn-codes.h.
Use mode_for_extraction rather than testing HAVE_insv/extv/extzv
and digging through the insn_data tables.
* Makefile.in: Update dependencies.
