Remove global call sets: combine.c
There shouldn't be many cases in which a useful hard register is
live across a call before RA, so we might as well keep things simple
and invalidate partially-clobbered registers here, in case the values
they hold leak into the call-clobbered part. In principle this is
a bug fix for TARGET_HARD_REGNO_CALL_PART_CLOBBERED targets,
but in practice it probably doesn't make a difference.

* combine.c: Include function-abi.h.
(record_dead_and_set_regs): Use insn_callee_abi to get the ABI
of the target of call insns. Invalidate partially-clobbered
registers as well as fully-clobbered ones.
