Rollup merge of #57729 - pnkfelix:issue-55748-pat-types-are-constraints-on-bindings-too, r=nikomatsakis 
extra testing of how NLL handles wildcard type `_`

test that wildcard type `_` is not duplicated by `type Foo<X> = (X, X);` and potentially instantiated at different types when used in type ascriptions in let bindings.

(NLL's handling of this for the type ascription *expression form* is currently broken, or at least differs from what AST-borrowck does. I'll file a separate bug about that. Its not something critical to address since that expression is guarded by `#![feature(type_ascription)]`.)

6007e6f649 Do not complain about non-existing fields after parse recovery 
When failing to parse struct-like enum variants, the ADT gets recorded
as having no fields. Record that we have actually recovered during
parsing of this variant to avoid complaing about non-existing fields
when actually using it.

817d074e54 Auto merge of #59250 - bovinebuddha:filter_ui_revision_tests, r=petrochenkov 
Filter ui revision tests

Updates UI test output filtering to also filter away test annotations for revisions:

Previously filtered: //~ ERROR [XXXX]
Now also filters: //[revision]~ ERROR [XXXX]

I reckon, if we have the one, we should have the other for consistency, its lack was probably an oversight (the existence of revision testing is not really well documented...)

Rollup merge of #59201 - lambda:remove-repr-simd-isize-usize-restriction, r=alexcrichton 
Remove restriction on isize/usize in repr(simd)

As discussed in #55078, there's no known reason for this restriction.

It's unlikely that repr(simd) will be stabilized in its current form, but
might as well remove some restrictions on it.

This removes the branch in `is_machine` which returns false for these types.
`is_machine` is only used for the repr(simd) type validation check.

Rollup merge of #59169 - tmandry:allow-features-flag, r=cramertj 
Add `-Z allow_features=...` flag

Adds a compiler option to allow only whitelisted features.

For projects on nightly that want to prevent feature-creep (and maybe, someday, move off of nightly). Not being able to enforce this has been a problem on Fuchsia and at other big companies.

This doesn't support filtering edition feature flags, but someone is welcome to add that if they need it.
