MIPS: To aid vector-based load ic work, we need to be able to handle the megamorphic load case in hydrogen.

Port r23772 (d6d07c5)

Original commit message:
Encapsulate megamorphic load/tail-call in hydrogen.

A simple approach is to wrap the probe activity in a hydrogen instruction.

The instruction is novel in that it always tail-calls away.

E.g. make sure that Int32Matcher matches only int32 constants, and
Float64Matcher matches only float64 constants.

Also remove the confusing CommonOperatorTraits, which are too easy
to use in a wrong way.
