This commit adds some new `LocalDecl` methods: - `with_source_info`, a most general constructor. - `new`, a variant of `with_source_info` which represents the most common use case. - `internal` a modifying method (like the already present `immutable`). It removes some old `LocalDecl` methods: - `new_internal` and `new_local`, because they're subsumed by the new methods. - `new_return_place`, because it was identical to `new_temp`. Finally, it cleans up all the use sites.
By boxing `local_info`.
By boxing `user_ty`.

LocalDeclcontributes 4-8% of peak heap memory usage on a range of benchmarks. This PR reduces its size from 128 bytes to 56 bytes on 64-bit, and does some clean-ups as well.r? @matthewjasper
