Rollup merge of #141811 - mejrs:bye_locals, r=compiler-errors
Unimplement unsized_locals Implements https://github.com/rust-lang/compiler-team/issues/630 Tracking issue here: https://github.com/rust-lang/rust/issues/111942 Note that this just removes the feature, not the implementation, and does not touch `unsized_fn_params`. This is because it is required to support `Box<dyn FnOnce()>: FnOnce()`. There may be more that should be removed (possibly in follow up prs) - the `forget_unsized` function and `forget` intrinsic. - the `unsized_locals` test directory; I've just fixed up the tests for now - various codegen support for unsized values and allocas cc ``@JakobDegen`` ``@oli-obk`` ``@Noratrieb`` ``@programmerjake`` ``@bjorn3`` ``@rustbot`` label F-unsized_locals Fixes rust-lang/rust#79409
