This test depends on the target-specific behavior of crt-static for musl
targets. However, running the testsuite on a musl host requires
setting `crt-static` to `false`, as it wouldn't otherwise be possible to
build rustc. This in turn will enable `-Ctarget-feature=-crt-static` for
all tests, mismatching the expected `+crt-static` for the musl target
tested in this testcase.
Since this test specifically tests the default value of `crt-static` for
the musl target, ignoring it entirely makes more sense than manually
setting `-Ctarget-feature=+crt-static` here, but both would be valid
approaches.

In a PR to emit warnings on misuse of `--print native-static-libs`,
we did not consider the matter of composing parts of build systems.
If you are not directly invoking rustc, it can be difficult to know
when you will in fact compile a staticlib, so making sure everyone
uses `--print native-static-lib` correctly can be just a nuisance.
This reverts the following commits:
- f66787a08d57dc1296619b314d2be596085bfeef
- 72a9219e82c157041bfc8dfd378c9cb2b09c0650
- 98bb597c05c32365abbd6898f278b097352774ed
- c59b70841c36277464b51161e3fcf12dfcb667e0
Next cycle we can reland a slightly more narrowly focused variant or one
that focuses on `--emit` instead of `--print native-static-libs`.
But in its current state, I am not sure the warning is very useful.

Can be fixed properly later by adding a new flag for non-exhaustive line annotation checking

Add unstable `--print=crate-root-lint-levels`
This PR implements `--print=crate-root-lint-levels` from MCP 833 https://github.com/rust-lang/compiler-team/issues/833.

- Document test intent to check for `-Whelp` suggestion if
`--print=lints` was specified.
- Move this test under `tests/ui/print-request/` and rename it to
`print-lints-help.rs` to better reflect what it is checking.

As an unstable print request.

I can't find any dedicated tests that actually exercises the stability
gating (via `-Z unstable-options`) of print requests, so here's a
dedicated one.
I coalesced `tests/ui/feature-gates/feature-gate-print-check-cfg.rs`
into this test, because AFAICT that print request is not feature gated,
but only `-Z unstable-options`-gated just like other unstable print
requests.

The deployment target environment variable is OS-specific, and if you're
in a place where you're asking `rustc` for the deployment target, you're
likely to also wanna know the environment variable.

People often parse `-vV` output to get to the host triple, which is
annoying to do. It's easier to just get it directly.
