The bulk of this change is changing most pattern insts to be `Always` rather than `AlwaysUnique` constants, so that they can be wrapped in `SpecificConstant`s to perform substitution. That then lets thunking rely much more on `SpecificConstant` wrappers instead of deep-copying the inst tree with modified types. This approach to thunking should scale better, particularly as things like form generics make function signatures more complex, because we can leverage the existing support for constant evaluation and substitution. Unfortunately, applying this approach to binding patterns will require more work; see the TODO near the top of `thunk.cpp` for details. --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>
