Update SIL devirtualization to handle begin_apply instructions.

In order to make this reasonable, I needed to shift responsibilities
around a little; the devirtualization operation is now responsible for
replacing uses of the original apply.  I wanted to remove the
phase-separation completely, but there was optimization-remark code
relying on the old apply site not having been deleted yet.

The begin_apply aspects of this aren't testable independently of
replacing materializeForSet because coroutines are currently never
called indirectly.
