copy any file from stage0/lib to stage0-sysroot/lib
With the LLVM 18 upgrade, the name of the LLVM library has been changed to something like `libLLVM.so.18.1-rust-1.78.0-beta`, which `is_dylib` function cannot determine as it only looks whether files are ending with ".so" or not.
This change resolves this problem by no longer doing that ".so" check, as we need all files from the stage0/lib as they are all dependency of rustc anyway.
Fixes#122913
Normalize the result of `Fields::ty_with_args`
We were only instantiating before, which would leak an AliasTy. I added a test case that reproduce the issue seen here:

Simplify trim-paths feature by merging all debuginfo options together
This PR simplifies the trim-paths feature by merging all debuginfo options together, as described in https://github.com/rust-lang/rust/issues/111540#issuecomment-1994010274.
And also do some correctness fixes found during the review.

CFI: Fix methods as function pointer cast
Fix casting between methods and function pointers by assigning a secondary type id to methods with their concrete self so they can be used as function pointers.
This was split off from #116404.

Eliminate `UbChecks` for non-standard libraries
The purpose of this PR is to allow other passes to treat `UbChecks` as constants in MIR for optimization after #122629.

Codegen const panic messages as function calls
This skips emitting extra arguments at every callsite (of which there
can be many). For a librustc_driver build with overflow checks enabled,
this cuts 0.7MB from the resulting shared library (see [perf]).
A sample improvement from nightly:
```
leaq str.0(%rip), %rdi
leaq .Lalloc_d6aeb8e2aa19de39a7f0e861c998af13(%rip), %rdx
movl $25, %esi

Errors started showing up, and I read somewhere that this might be
because of old ninja versions. This ninja version is indeed *ancient*.

Correctly get complete intra-doc link data
Fixes https://github.com/rust-lang/rust/issues/123158.
The problem was that we didn't take into account cases where there would be content other than backticks into the intra doc link definition.
r? `@notriddle`
Use compiletest directives instead of manually checking TARGET / tools
Changes:
- Accept `ignore-wasm32-wasip1` and `needs-wasmtime` directives.
- Add support for needing `wasmtime` as a runner.
- Update wasm/compiler_builtin tests to use compiletest directives over manual checks.
Don't check match scrutinee of postfix match for unused parens
We only check the scrutinees of block-like constructs and a few others (return/index/assign/method calls). Just don't do it for postfix match at all.
Fixes#123064
