Add targetm.insn_cost hook
This adds a new hook that the insn_cost function uses if a target has
implemented it (it uses the old pattern_cost nee insn_rtx_cost if not).
* target.def (insn_cost): New hook.
* doc/tm.texi.in (TARGET_INSN_COST): New hook.
* doc/tm.texi: Regenerate.
* rtlanal.c (insn_cost): Use the new hook.
