…didates instead of param_env candidates

Building a dozen separate regexps for each test in compiletest consumes significant amounts of CPU cycles.
Using `RUSTC_FORCE_INCR_COMP_ARTIFACT_HEADER` stabilizes hashes calcuated for the individual tests so
no test-dependent normalization is needed. Hashes for the standard library still change so some
normalizations are still needed.

Also ignore clippy's "collapsible if..." lints.

Implement raw-dylib support for windows-gnu

Add support for `#[link(kind = "raw-dylib")]` on windows-gnu targets.  Work around binutils's linker's inability to read import libraries produced by LLVM by calling out to the binutils `dlltool` utility to create an import library from a temporary .DEF file; this approach is effectively a slightly refined version of ```@mati865's``` earlier attempt at this strategy in PR rust-lang#88801.  (In particular, this attempt at this strategy adds support for `#[link_ordinal(...)]` as well.)

In support of rust-lang#58713.

Prefer projection candidates instead of param_env candidates for Sized predicates

Fixes rust-lang#89352

Also includes some drive by logging and verbose printing changes that I found useful when debugging this, but I can remove this if needed.

This is a little hacky - but imo no more than the rest of `candidate_should_be_dropped_in_favor_of`. Importantly, in a Chalk-like world, both candidates should be completely compatible.

Override rustc version in ui and mir-opt tests to get stable hashes

Building a dozen separate regexps for each test in compiletest consumes significant amounts of CPU cycles.

UI test timings on my machine:

OLD: 39.63s
NEW: 30.27s

Export `tcp::IntoIncoming`

Added in rust-lang#88339 but not publicly exported.

Make `opt_const_param_of` work in the presence of `GenericArg::Infer`

highly recommend viewing the first and second commits on their own rather than looking at file changes 🤣

Because we filtered args down to just const args we would ignore `GenericArg::Infer` which made us get a `arg_index` which was wrong by however many const `GenericArg::Infer` came previously

[example](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=46dba6a53aca6333028a10908ef16e0b) of the [bugs](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=a8eebced26eefa4119fc2e7ae0c76de6) fixed.
