Richard Smith 812cc1e032 Add SpecificInst to represent a specific version of a template-dependent instruction (#7726) 
Replace `refine_type_action` with `refine_inst_action`, and generate a
`specific_inst` instead of an `as_compatible` to represent the specific
version of an instruction that's used as an input to a template action.
This gives us a place to handle other properties of the instruction that
might vary from generic to specific beyond its type, such as its
constant value and its expression category.

For now, we provide a non-template-dependent constant value to the
`specific_inst` in addition to the non-template-dependent type we have
traditionally provided. This doesn't seem to matter for any current
actions, but sets us up to better handle future actions. The
`specific_inst` representation also allows downstream consumers of the
instruction to track which specific they should be requesting
information from. Providing a correct expression category for
`specific_inst` will be handled in a future PR.
