ifcvt: Run second pass if it is possible to omit a temporary.
If one of the to-be-converted SETs requires the original comparison
(i.e. in order to generate a min/max insn) but no other insn after it
does, we can omit creating temporaries, thus facilitating costing.
gcc/ChangeLog:
* ifcvt.cc (noce_convert_multiple_sets_1): New function.
(noce_convert_multiple_sets): Call function a second time if we can
improve the first try.
