  [Dominator] Add findNearestCommonDominator() for Instructions (NFC)

This is a recurring pattern: We want to find the nearest common
dominator (instruction) for two instructions, but currently only
provide an API for the nearest common dominator of two basic blocks.

Add an overload that accepts and return instructions.
