SILBuilder: add an API to insert _after_ an instruction.

Browse Source

Also change FullApplySite::insertAfterInvocation/insertAfterFullEvaluation to directly pass a SILBuilder instead of just an insertion point to the callback.
This makes more sense (given the function names) and simplifies the usages.

It's a NFC.
