[Bug middle-end/21273] New: gensupport.c:collect_insn_data doesn't consider the constraints of match_scratch

[hp at gcc dot gnu dot org]

collect_insn_data is supposed to figure out the max number of constraints, but
doesn't look at the constraints of match_scratch (only match_operand).
Though match_scratch is unlikely to be the only specified constraint in a
pattern (and so unlikely to affect any target), it's nevertheless a bug.
