Break out of the correct number of scopes in loops
We were incorrectly breaking out of one too many drop scopes when
generating MIR for loops and breakable blocks, resulting in use after
free and associated borrow checker warnings.
This wasn't noticed because the scope that we're breaking out of twice
is only used for temporaries that are created for adjustments applied to
the loop. Since loops generally propagate coercions to the `break`
expressions, the only case we see this is when the type of the loop is a
smart pointer to a trait object.
Closes#62312
Improve error span for async type inference error
Fixes#62382
Previously, we would point at the spawn of the 'await' expression,
instead of the actual expression with an unknown type.
Remove io::Result from syntax::print
Since we're now writing directly to the vector, there's no need to
thread results through the whole printing infrastructure
This is useful for getting the total compilation time at the end.
To do this, the patch changes `print_time_passes_entry` to not increment
the depth, which means that `print_time_passes_entry_internal` is no
longer needed.
Update the `rust-installer` submodule
This pulls in a commit which uses parallel xz encoding which should
hopefully help shave some time off the dist builders which spend an
inordinate amount of time compressing this data.
