Search other library paths when loking for link objects
Support the case when link objects are not located in Rust sysroot
but in other locations which could be specify through library paths.
fix trait objects with a Self-containing projection values
Fixes#56288.
This follows ALT2 in the issue.
beta-nominating since this is a regression.

Fix various aspects around `let` bindings inside const functions
* forbid `let` bindings in const contexts that use short circuiting operators
* harden analysis code against derefs of mutable references
Initially this PR was about stabilizing `let` bindings, but too many flaws were exposed that need some more testing on nightly
Fixes rustdoc-js tests by teaching tester.js how to handle single-line js comments.
Also, added speculative support for template strings, and warnings for future debuggers.
add coherence future-compat warnings for marker-only trait objects
The future-compat warnings break code that assumes that `dyn Send + Sync !=
dyn Sync + Send`, and are the first step in making them equal. cc #33140.
Note: this lint should be made to default-warn before we merge. It is deny only for the crater run.

When building a distributed compiler on Linux where we use ThinLTO to
create the LLVM shared object this commit switches the compiler to
dynamically linking that LLVM artifact instead of statically linking to
LLVM. The primary goal here is to reduce CI compile times, avoiding two+
ThinLTO builds of all of LLVM. By linking dynamically to LLVM we'll
reuse the one ThinLTO step done by LLVM's build itself.
Lots of discussion about this change can be found [here] and down. A
perf run will show whether this is worth it or not!

This brings in a few updates:
* Update wasm intrinsic naming for atomics
* Update and reimplement most simd128 wasm intrinsics
* Other misc improvements here and there, including a small start to
AVX-512 intrinsics
