Align attr fixes
- Remove references to the superseded `repr(align)` syntax
- Allow the attribute on fn items in `extern` blocks
- Test attribute in combination with `async fn` and `dyn`

Do not unify borrowed locals in CopyProp.
Instead of trying yet another scheme to unify borrowed locals in CopyProp, let's just stop trying. We had already enough miscompilations because of this.
I'm convinced it's possible to have both unification of some borrowed locals and soundness, but I don't have a simple and convincing formulation yet.

rustc_builtin_macros: Make sure registered attributes stay sorted
As with the list of builtin macros, use tidy to make sure the list of
builtin attributes stays sorted.
|
|
Organize macro tests a bit more
- Move some macro parsing tests from `tests/ui/parser` to `tests/ui/parser/macro`.
- Most macro tests use `macro` in the name, making it easy to find and run tests relevant to macros. However, a few use `mbe` instead. Rename those to say `macro`.

tidy: use --bless for tidy spellcheck instead of spellcheck:fix
previous behavior was inconsistent with existing extra checks.
unsure if this needs a change tracker entry or a warning for people who try to use the old behavior.
unsure if we should call this `spellcheck:lint` for consistency.
making this consistent is a prerequisite for https://github.com/rust-lang/rust/pull/143398

use `is_multiple_of` and `div_ceil`
In tricky logic, these functions are much more informative than the manual implementations. They also catch subtle bugs:
- the manual `is_multiple_of` often does not handle division by zero
- manual `div_ceil` often does not consider overflow
The transformation is free for `is_multiple_of` if the divisor is compile-time known to be non-zero. For `div_ceil` there is a small cost to considering overflow. Here is some assembly https://godbolt.org/z/5zP8KaE1d.

mbe: Defer checks for `compile_error!` until reporting an unused macro rule
The current MBE parser checks rules at initial parse time to see if their RHS has `compile_error!` in it, and returns a list of rule indexes and LHS spans that don't map to `compile_error!`, for use in unused macro rule checking.
Instead, have the unused macro rule reporting ask the macro for the rule to report, and let the macro check at that time. That avoids checking rules unless they're unused.
In the process, refactor the data structure used to store macro rules, to group the LHS and RHS (and LHS span) of each rule together, and refactor the unused rule tracking to only track rule indexes.
This builds atop a couple of minor MBE refactors. I would suggest reviewing commit-by-commit.
The overall result is a further simplification of the macro code.

The `macro` directory contains most of the macro tests, but not all of
them; move the remainder into `macro`.

The MBE parser checks rules at initial parse time to see if their RHS
has `compile_error!` in it, and returns a list of rule indexes and LHS
spans that don't map to `compile_error!`, for use in unused macro rule
checking.
Instead, have the unused macro rule reporting ask the macro for the rule
to report, and let the macro check at that time. That avoids checking
rules unless they're unused.
In the process, refactor the data structure used to store macro rules,
to group the LHS and RHS (and LHS span) of each rule together, and
refactor the unused rule tracking to only track rule indexes.
This ends up being a net simplification, and reduction in code size.

The parser repeatedly invokes the `parse` function, constructing a
one-entry vector, and assuming that the return value will be a one-entry
vector. Add a helper for that case. This will simplify adding additional
callers, and put all the logic in one place to allow potential future
simplification of the one-TT case.

Remove yields_in_scope from the scope tree.
I believe this has not been in use since we removed the HIR-based generator interior type computation.

Stop using `Key` trait unnecessarily
Few places where the `Key` trait was being used but not really for a useful reason. This fixes those usages.
Namely, `<Ty as Key>::default_span()` is `DUMMY_SP` anyways.

Canonicalize input ty/ct infer/placeholder in the root universe
We shouldn't care what universe the inputs are, since we only ever do the leak check on the universes instantiated after entering the canonical binder.
