Remove invalid compile-fail tests related to !
...
These tests check for the old error messages "`return` in a function
declared as diverging" and "computation may converge in a function
declared as diverging". The first of these is now invalid as `return` is
permitted in functions that return `!`. The second of these is subsumed
by the "mismatched types" error.

[MIR] Add explicit SetDiscriminant StatementKind for deaggregating enums
cc #35186
To deaggregate enums, we need to be able to explicitly set the discriminant. This PR implements a new StatementKind that does that.
I think some of the places that have `panics!` now could maybe do something smarter.
