Introduce API for stack state modifying instructions

Authored by anna on Sep 16 2021, 1:16 PM.



This patch introduces an API to identify instructions that modify the
function stack state. The name here may not be accurate enough, but the
idea is to use a common API for transforms that move instructions (see
updated transforms).

This is also used in an upcoming change in InstCombine.
