* rtlanal.c (insn_rtx_cost): New function, moved and renamed from
combine.c's combine_insn_cost.
* rtl.h (insn_rtx_cost): Prototype here.
* combine.c (combine_insn_cost): Delete function.
(combine_validate_cost): Update callers of combine_insn_cost to
call insn_rtx_cost instead.
(combine_instructions): Likewise. Use NONJUMP_INSN_P to avoid
requesting the rtx_cost of call and/or jump instructions.
* ifcvt.c (total_bb_rtx_cost): Use insn_rtx_cost instead of calling
rtx_cost directly. Don't request/use the cost of call or jump
instructions. Return -1 if the cost of any instruction can't be
determined (or the BB contains a function call).
(find_if_case_1): Abort transformation if total_bb_rtx_cost returns
-1 (i.e. can't determine the cost of any instruction or the basic
block contains a subroutine call).
(find_if_case_2): Likewise.
