1f02d1f880 Allow for multiple legalization patterns for the same opcode.
Each input pattern can have a predicate in addition to an opcode being
matched. When an opcode has multiple patterns, execute the first pattern
with a true predicate.

The predicates can be type checks or instruction predicates checking
immediate fields.
