3639341685 Default diverging types based on feature gate.

5096a8c5c0 Control usage of ! through a feature gate. 
Adds the `bang_type` feature gate. `!` in a non-return-type position now
relies on that feature.

ba65d2e15b 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.

This test probably adds negative value other than historical amusement.

[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.

db16909ae3 exclude #![no_builtins] crates from LTO 
this prevents intrinsics like `memcpy` from being mis-optimized to
infinite recursive calls when LTO is used.
