95181ae170 Update compiler-builtins to 0.1.152 
Includes the following changes related to unordered atomics:

* Remove element_unordered_atomic intrinsics [1]

There are a handful of other small changes, but nothing else
user-visible.

8c1b49d5e9 Use public-dependencies in all sysroot crates 
In [1], most dependencies of `std` and other sysroot crates were marked
private, but this did not happen for `alloc` and `test`. Update these
here, marking public standard library crates as the only non-private
dependencies.

95ecf0c262 Update compiler_builtins to 0.1.138 and pin it 
This updates to a new version of builtins that includes [1], which was
the last blocker to us enabling `f128` tests on all platforms 🎉.

With this update, also change to pinning the version with `=` rather
than using the default carat versioning. This is meant to ensure that
`compiler-builtins` does not get updated as part of the weekly
`Cargo.lock` update, since updates to this crate need to be intentional:
changes to rust-lang/rust and rust-lang/compiler-builtins sometimes need
to be kept in lockstep, unlike most dependencies, and sometimes these
updates can be problematic.

80d8270d84 Auto merge of #125016 - nicholasbishop:bishop-cb-112, r=tgross35 
Update compiler_builtins to 0.1.114

The `weak-intrinsics` feature was removed from compiler_builtins in https://github.com/rust-lang/compiler-builtins/pull/598, so dropped the `compiler-builtins-weak-intrinsics` feature from alloc/std/sysroot.

In https://github.com/rust-lang/compiler-builtins/pull/593, some builtins for f16/f128 were added. These don't work for all compiler backends, so add a `compiler-builtins-no-f16-f128` feature and disable it for cranelift and gcc.

7fb81229d3 Rollup merge of #123803 - Sp00ph:shrink_to_fix, r=Mark-Simulacrum 
Fix `VecDeque::shrink_to` UB when `handle_alloc_error` unwinds.

Fixes #123369

For `VecDeque` it's relatively simple to restore the buffer into a consistent state so this PR does just that.

Note that with its current implementation, `shrink_to` may change the internal arrangement of elements in the buffer, so e.g. `[D, <uninit>, A, B, C]` will become `[<uninit>, A, B, C, D]` and `[<uninit>, <uninit>, A, B, C]` may become `[B, C, <uninit>, <uninit>, A]` if `shrink_to` unwinds. This shouldn't be an issue though as we don't make any guarantees about the stability of the internal buffer arrangement (and this case is impossible to hit on stable anyways).

This PR also includes a test with code adapted from #123369 which fails without the new `shrink_to` code. Does this suffice or do we maybe need more exhaustive tests like in #108475?

not generally up to date/useful information, we should remove it from
