[PR target/60657] [P1 regression] Fix operand predicates for a few ARM insns

2014-04-03 Thread Jeff Law
As noted in the PR, there are a few insns in the ARM backend which use const_int_operand as a predicate, but which have constraints like "I" or "M". With the predicate accepting all constants, it's possible for a pass such as combine to create an insn where the constant operand matches the
