Rollup merge of #62735 - petrochenkov:galloc, r=alexcrichton 
Turn `#[global_allocator]` into a regular attribute macro

It was a 99% macro with exception of some diagnostic details.

As a result of the change, `#[global_allocator]` now works in nested modules and even in nameless blocks.

890881f8f4 Auto merge of #60340 - mgeier:cap-vs-capacity, r=alexcrichton 
Rename .cap() methods to .capacity()

As mentioned in #60316, there are a few `.cap()` methods, which seem out-of-place because such methods are called `.capacity()` in the rest of the code.

This PR renames them to `.capacity()` but leaves `RawVec::cap()` in there for backwards compatibility.

I didn't try to mark the old version as "deprecated", because I guess this would cause too much noise.

Remove cfg(bootstrap) code for array implementations 
In PR #62435 ("Use const generics for array impls [part 1]") the old
macro-based implementations were not removed but still used with
`cfg(bootstrap)` since the bootstrap compiler had some problems with
const generics at the time. This does not seem to be the case anymore,
so there is no reason to keep the old code.

Rollup merge of #62869 - matklad:feature-gate, r=Mark-Simulacrum 
add rustc_private as a proper language feature gate

At the moment, `rustc_private` as a (library) feature exists by
accident: `char::is_xid_start`, `char::is_xid_continue` methods in
libcore define it.

cc https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/How.20to.20declare.20new.20langauge.20feature.3F

I don't know if this is at all reasonable, but at least tests seem to pass locally. That probably means that we can remove/rename to something more resonable the feature in libcore in the next release?

Rollup merge of #62799 - RalfJung:uninit-array, r=Centril 
use const array repeat expressions for uninit_array

With a first implementation of https://github.com/rust-lang/rust/issues/49147 having landed, we can make this macro nicer and phase it out with the next bootstrap bump.

However, to make this work, we have to mark `MaybeUninit::uninit()` as promotable. I do feel uneasy about promoting stuff involving uninitialized memory, but OTOH no *operation* on `MaybeUninit` is promotable, so maybe this is okay?

e34d4ae869 Auto merge of #61339 - jridgewell:pointer-alignment, r=BurntSushi 
Optimize pointer alignment in utf8 validation

This uses (and reuses) the u8 arrays's inherent block alignment when checking whether the current index is block aligned.

I initially thought that this would just move the expensive `align_offset` call out of the while loop and replace it with a subtraction and bitwise AND. But it appears this optimizes much better, too...
