Reimplement DestinationPropagation according to live ranges.
This PR reimplements DestinationPropagation as a problem of merging live-ranges of locals. We merge locals that have disjoint live-ranges. This allows merging several locals in the same round by updating live range information.
Live ranges are mainly computed using the `MaybeLiveLocals` analysis. The subtlety is that we split each statement and terminator in 2 positions. The first position is the regular statement. The second position is a shadow, which is always more live. It encodes partial writes and dead writes as a local being live for half a statement. This half statement ensures that writes conflict with another local's writes and regular liveness.

Introduce PlaceContext::may_observe_address.
A small utility method to avoid open-coding the logic in several MIR opts.

feat(std): emulate flock for solaris via fcntl
Upstream Solaris flock emulation to libstd from cargo.
This is borrowed from
https://github.com/rust-lang/cargo/blob/3b379fcc541b39321a7758552d37e5e0cc4277b9/src/cargo/util/flock.rs#L502-L536 which was implemented by an Oracle employee.
The code has been in cargo since 2022-12.
Python's `fcntl.flock` emulates like this as well: https://github.com/python/cpython/blob/c919d02edecfe9d75fe374756fb8aa1db8d95f55/Modules/fcntlmodule.c#L337-L400
We did the same thing in
https://github.com/rust-lang/rust/blob/0d0f4eac8b98133e5da6d3604d86a8f3b5a67844/compiler/rustc_data_structures/src/flock/unix.rs#L13-L39
However, should we just always falls back to fcntl for all Unix, instead of "unsupported"?

Misc LTO cleanups
Follow up to https://github.com/rust-lang/rust/pull/145955.
* Remove want_summary argument from `prepare_thin`.
Since https://github.com/rust-lang/rust/pull/133250 ThinLTO summary writing is instead done by `llvm_optimize`.
* Two minor cleanups

fix: offline rustdoc html missing favicon
As discussed in the rust-lang/rust#146149 the doc was missing the favicon icon when build locally and viewed on a browser. I changed the relative path and also now we explicitly copy both SVG and PNG.

Add amdgpu test for addrspacecasting global vars and the gpu-kernel calling convention
Add two tests that can now be added, as the amdgpu is merged.
- Global variables are casted to the default address space since rust-lang/rust#135026
- gpu-kernel calling convention, translatos to amdgpu_kernel rust-lang/rust#135047
Tracking issue: rust-lang/rust#135024

GVN: Allow reusing aggregates if LHS is not a simple local.
This resolves a FIXME in the code. I don't see a reason not to allow this.

LorrensP-2158466:miri-float-nondet-foreign-items-take2, r=RalfJung
Miri: non-deterministic floating point operations in foreign_items
Take 2 of rust-lang/rust#143906. The last 2 commits are what changed compared to the original pr.
Verified the tests using (fish shell):
```fish
env MIRIFLAGS="-Zmiri-max-extra-rounding-error -Zmiri-many-seeds" ./x miri --no-fail-fast std core coretests -- f32 f64

Revert "Add LSX accelerated implementation for source file analysis"

Use `Itertools::all_equal_value()` where applicable
Just a small cleanup.
We already have `itertools` as a dep in these crates, so might as well use another of its features.
Makes the code simpler IMHO :)

lint ImproperCTypes: refactor linting architecture (part 1)
This is the first PR in an effort to split rust-lang/rust#134697 into individually-mergeable parts.
This one focuses on properly packaging the lint and its tests, as well as properly separate the "linting" and "type-checking" code.
There is exactly one user-visible change: the safety of `Option<Box<FFISafePointee>>` is now the same in `extern` blocks and function definitions: it is safe.
r? `@tgross35` because you are already looking at the original

Simplify rustdoc-gui tester by calling directly browser-ui-test
The output and handling of `browser-ui-test` is now mostly the same as we did manually, so no need to keep our wrapper anymore. Lot of code removed! \o/
