Simply shift the bitcast from the store to the load, so that
we can use the destination type. I'm not sure the bitcast is
really necessary, but keeping it for now.
I'm not really sure what is wrong here, but I was getting load
type mismatches in the debuginfo code (which is the only place
using this function).
Replacing the project_deref() implementation with a generic
load_operand + deref did the trick.
This makes load generation compatible with opaque pointers.
The generation of nontemporal copies still accesses the pointer
element type, as fixing this requires more movement.
Unescaped command-line arguments for Windows
Some Windows commands, expecially `cmd.exe /c`, have unusual quoting requirements which are incompatible with default rules assumed for `.arg()`.
This adds `.unquoted_arg()` to `Command` via Windows `CommandExt` trait.
Fixes#29494
Use #[track_caller] in const panic diagnostics.
This change stops const panic diagnostics from reporting inside #[track_caller] functions by skipping over them.
Change linked tracking issue for more_qualified_paths
This updates the linked tracking issue for the `more_qualified_paths` feature from the implementation PR #80080 to an actual tracking issue #86935.
Fix double warning about illegal floating-point literal pattern
This PR fixes#86600. The problem is that the `ConstToPat` struct contains a field `include_lint_checks`, which determines whether lints should be emitted or not, but this field is currently not obeyed at one point, leading to a warning being emitted more than once. I have fixed this behavior here.
Account for capture kind in auto traits migration

2229: Reduce the size of closures with `capture_disjoint_fields`
One key observation while going over the closure size profile of rustc
was that we are disjointly capturing one or more fields starting at an
immutable reference.
Disjoint capture over immutable reference doesn't add too much value
because the fields can either be borrowed immutably or copied.
One possible edge case of the optimization is when a fields of a struct
have a longer lifetime than the structure, therefore we can't completely
get rid of all the accesses on top of sharef refs, only the rightmost
one. Here is a possible example:
```rust
struct MyStruct<'a> {
a: &'static A,
b: B,
c: C<'a>,
}
fn foo<'a, 'b>(m: &'a MyStruct<'b>) -> impl FnMut() + 'static {
let c = || drop(&*m.a.field_of_a);
// Here we really do want to capture `*m.a` because that outlives `'static`
// If we capture `m`, then the closure no longer outlives `'static'
// it is constrained to `'a`
}
```
