Clean up query cache code
There are a couple of queries for which we do not promote saved results, which have been removed from caching here. This was likely the cause of the regression in https://github.com/rust-lang/rust/pull/57293#issuecomment-476421298.

Update musl to 1.1.22
This is the latest available version. I noticed Rust wasn't using the
latest version when I attempted to have Cargo link object files produced
outside of Cargo / Rust's toolchain and was getting missing symbol
errors. Those missing symbols were added in 1.1.21 and 1.1.22.
I'm not fully sure of the implications of this change or how
comprehensive the test coverage is. Upstream changes in 1.1.21 and
1.1.22 can be found at
https://git.musl-libc.org/cgit/musl/tree/WHATSNEW?h=v1.1.22&id=e97681d6f2c44bf5fa9ecdd30607cb63c780062e#n1989.
Normalization can leave some type-vars unresolved in its return type.
Make sure to resolve them so we have an infcx-independent type that can
be used with `needs_drop`.
Fixes#61402.

Avoid mem::uninitialized() in std::sys::unix
For `libc` types that will be initialized in FFI calls, we can just use
`MaybeUninit` and then pass around raw pointers.
For `sun_path_offset()`, which really wants `offset_of`, all callers
have a real `sockaddr_un` available, so we can use that reference.

Add `--pass $mode` to compiletest through `./x.py`
Adds a flag `--pass $mode` to compiletest, which is exposed through `./x.py`.
When `--pass $mode` is passed, `{check,build,compile,run}-pass` tests will be forced to run under the given `$mode` unless the directive `// ignore-pass` exists in the test file.
The modes are explained in https://github.com/rust-lang/rust/pull/61778:
- `check` has the same effect as `cargo check`
- `build` or `compile` have the same effect as `cargo build`
- `run` has the same effect as `cargo run`
On my machine, `./x.py -i test src/test/run-pass --stage 1 --pass check` takes 38 seconds whereas it takes 2 min 7 seconds without `--pass check`.

Revert "Set test flag when rustdoc is running with --test option"
Reverts https://github.com/rust-lang/rust/pull/59940.
It caused doctests in this repository to no longer be tested including all of the core crate.
