Replaces using `ResumeTy` / `get_context` in favor of using `&'static mut Context<'_>`.

Usage of the `'static` lifetime here is technically "cheating", and replaces
the raw pointer in `ResumeTy` and the `get_context` fn that pulls the
correct lifetimes out of thin air.

This isn't overriding anything, because the sidebar never has a margin or
padding on it.

interpret: clobber return place when calling function

Makes sure the callee cannot observe the previous contents of the return place, and the caller cannot read any of the old return place contents even if the function unwinds.

I don't think we can test for this though, that would require some strange hand-written MIR.

Remove unneeded field from `SwitchTargets`

This had a fixme already. The only change in behavior is that the mir dumps now no longer contains labels for the types of the integers on the edges of a switchint:

Before:

After:

I don't think that's a problem though. The information is still available to a user that really cares by checking the type of `_2`, so it honestly feels like a bit of an improvement to me.

r? mir

remove no-op 'let _ = '

Also see the discussion at rust-lang#93563 (comment).

I don't know why these `Drop` implementations exist to begin with, given that their body does literally nothing, but did not want to change that. (It might affect dropck.)

Fix --pass in compiletest

This makes `x test src/test/mir-opt --pass run` actually do the thing it says it does. The resulting tests do not pass, I'll fix that in a follow up.

Replace usage of `ResumeTy` in async lowering with `Context`
