cmd/compile/internal/ssa: correct type of ARM64 conditional instructions

The CCMP, CCMN, CCMPconst, and related instructions in ARM64Ops.go
were incorrectly set to type "Flag". This non-existent type caused
compilation failures during the "lower" and "late lower" passes.

Change them to the correct type, "Flags".
