Rollup merge of #114558 - Enselic:lifetime-diagnostic-fixed, r=cjgillot 
Remove FIXME about NLL diagnostic that is already improved

The FIXME was added in #46984 when the diagnostic message looked like this:

    // FIXME(#46983): error message should be better
    &s.0 //~ ERROR free region `` does not outlive free region `'static`

The message was improved in #90667 and now looks like this:

    &s.0 //~ ERROR lifetime may not live long enough

but the FIXME was not removed. The issue #46983 about that diagnostics should be improved has been closed. We can remove the FIXME now.

(This PR was made for #44366.)

Rollup merge of #114556 - Enselic:issue-numbers-enforced, r=compiler-errors 
Issue numbers are enforced on active features; remove FIXME

Since https://github.com/rust-lang/rust/pull/51090 tidy enforces that active features have an issue number, so remove the FIXME.

This PR is part of #44366 which is E-help-wanted.

Rollup merge of #114550 - dtolnay:globalalloc, r=compiler-errors 
Generate better function argument names in global_allocator expansion

Generated code for `#[global_allocator] static ALLOCATOR: Allocator = Allocator;`&mdash;

**Before:**

```rust
const _: () = {
    #[rustc_std_internal_symbol]
    unsafe fn __rust_alloc(arg0: usize, arg1: usize) -> *mut u8 {
        ::core::alloc::GlobalAlloc::alloc(
            &ALLOCATOR,
            ::core::alloc::Layout::from_size_align_unchecked(arg0, arg1),
        )
    }
    #[rustc_std_internal_symbol]
    unsafe fn __rust_dealloc(arg0: *mut u8, arg1: usize, arg2: usize) -> () {
        ::core::alloc::GlobalAlloc::dealloc(
            &ALLOCATOR,
            arg0,
            ::core::alloc::Layout::from_size_align_unchecked(arg1, arg2),
        )
    }
    #[rustc_std_internal_symbol]
    unsafe fn __rust_realloc(
        arg0: *mut u8,
        arg1: usize,
        arg2: usize,
        arg3: usize,
    ) -> *mut u8 {
        ::core::alloc::GlobalAlloc::realloc(
            &ALLOCATOR,
            arg0,
            ::core::alloc::Layout::from_size_align_unchecked(arg1, arg2),
            arg3,
        )
    }
    #[rustc_std_internal_symbol]
    unsafe fn __rust_alloc_zeroed(arg0: usize, arg1: usize) -> *mut u8 {
        ::core::alloc::GlobalAlloc::alloc_zeroed(
            &ALLOCATOR,
            ::core::alloc::Layout::from_size_align_unchecked(arg0, arg1),
        )
    }
};
```

**After:**

```rust
const _: () = {
    #[rustc_std_internal_symbol]
    unsafe fn __rust_alloc(size: usize, align: usize) -> *mut u8 {
        ::core::alloc::GlobalAlloc::alloc(
            &ALLOCATOR,
            ::core::alloc::Layout::from_size_align_unchecked(size, align),
        )
    }
    #[rustc_std_internal_symbol]
    unsafe fn __rust_dealloc(ptr: *mut u8, size: usize, align: usize) -> () {
        ::core::alloc::GlobalAlloc::dealloc(
            &ALLOCATOR,
            ptr,
            ::core::alloc::Layout::from_size_align_unchecked(size, align),
        )
    }
    #[rustc_std_internal_symbol]
    unsafe fn __rust_realloc(
        ptr: *mut u8,
        size: usize,
        align: usize,
        new_size: usize,
    ) -> *mut u8 {
        ::core::alloc::GlobalAlloc::realloc(
            &ALLOCATOR,
            ptr,
            ::core::alloc::Layout::from_size_align_unchecked(size, align),
            new_size,
        )
    }
    #[rustc_std_internal_symbol]
    unsafe fn __rust_alloc_zeroed(size: usize, align: usize) -> *mut u8 {
        ::core::alloc::GlobalAlloc::alloc_zeroed(
            &ALLOCATOR,
            ::core::alloc::Layout::from_size_align_unchecked(size, align),
        )
    }

Steal MIR for CTFE when possible.
