Decode qualifs for associated const defaults
Fixes #71734.
We encode qualifs for associated constants, but never expected to decode the qualifs for defaulted associated consts. Fix this, and test that associated const defaults have the correct qualifs cross-crate.

Implement RFC 2523, `#[cfg(version(..))]`
Hi! This is my first contribution to rust, I hope I didn't miss anything. I tried to implement this feature so that `#[cfg(version(1.44.0))]` works but the parser was printing an error that I wasn't sure how to fix so I just opted for implementing `#[cfg(version("1.44.0"))]` (note the quotes).

Extract stamp testing for LLVM
The extracted function can be used by the rest of bootstrap to detect if we've
already built an up-to-date LLVM (and so it's safe for us to either request it
or pretend it exists).

This is a follow-up to https://github.com/rust-lang/rust/pull/70881 that also silences these warnings when deny_warnings is off. They otherwise spam my screen during development and make it hard to see actual warnings.

wf: handle "livelock" checking before reaching `WfPredicates::compute`.
For `wf::obligations`'s "livelock" handling, this PR shouldn't cause any behavioral changes, as the check moved to it should be equivalent to the old one in `WfPredicates::compute`.
However, it fixes #70168 by making *other* users of `WfPredicates::compute` (that is, `wf::predicate_obligations` and `compute`'s own upvar handling) correct for `ty::Infer`, in that they now get a `WellFormed(ty::Infer(_))` obligation instead of silently ignoring the type.

Rename `bitcode-in-rlib` option to `embed-bitcode`
This commit finishes work first pioneered in #70458 and started in #71528.
The `-C bitcode-in-rlib` option, which has not yet reached stable, is
renamed to `-C embed-bitcode` since that more accurately reflects what
it does now anyway. Various tests and such are updated along the way as
well.
This'll also need to be backported to the beta channel to ensure we
don't accidentally stabilize `-Cbitcode-in-rlib` as well.

Split out from #69406
Since the other PR is having memory problems with `parallel-compiler = true`, figured I should split this out. Surprisingly, this actually changes some errors, and I'm not quite sure why.

Avoid duplicating code for each query
There are at the moment roughly 170 queries in librustc.
The way `ty::query` is structured, a lot of code is duplicated for each query.
I suspect this to be responsible for a part of librustc'c compile time.
The first part of this PR reduces the amount of code generic on the query,
replacing it by code generic on the key-value types. I can split it out if needed.
In a second part, the non-inlined methods in the `QueryAccessors` and `QueryDescription` traits
are made into a virtual dispatch table. This allows to reduce even more the number of generated
functions.
This allows to save 1.5s on check build, and 10% on the size of the librustc.rlib.
(Attributed roughly half and half).
My computer is not good enough to measure properly compiling time.
I have no idea of the effect on performance. A perf run may be required.
