hook for targets to override if there are instructions that are only
trivially rematerializable with specific operands (i.e. constant pool
loads).

with a general target hook to identify rematerializable instructions. Some
instructions are only rematerializable with specific operands, such as loads
from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
mechanism.
