The test checks that we reuse the CGU of a crate when the implementation
details of an `extern crate` have changed.

Revert parts of #66405.
Because PR #66405 caused major performance regressions in some cases.
That PR had five commits, two of which affected performance, and three
of which were refactorings. This change undoes the performance-affecting
changes, while keeping the refactorings in place.
Fixes#67454.

Use function attribute "frame-pointer" instead of "no-frame-pointer-elim"
LLVM 8 ([D56351](http://reviews.llvm.org/D56351)) introduced "frame-pointer". In LLVM 10 (D71863),
"no-frame-pointer-elim"/"no-frame-pointer-elim-non-leaf" will be
ignored.
-----
In the LLVM monorepo, run `git show origin/release/8.x:llvm/lib/CodeGen/TargetOptionsImpl.cpp` to see that `"frame-pointer"` is available since LLVM 8.
parser: reduce diversity in error handling mechanisms
Instead of having e.g. `span_err`, `fatal`, etc., we prefer to move towards uniformly using `struct_span_err` thus making it harder to emit fatal and/or unstructured diagnostics.
This PR also de-fatalizes some diagnostics.

Extract `rustc_ast_lowering` crate from `rustc`
Working towards https://github.com/rust-lang/rust/issues/65031.
This PR moves `src/librustc/hir/lowering{/, .rs}` to its own crate (`librustc_ast_lowering`) which is very self-contained (only `fn lower_crate` and `trait Resolver` are exposed).

Support `-Z ui-testing=yes/no`
`ui-testing` is now a boolean option (`-Z ui-testing=yes/no`) and can be specified multiple times with later values overriding earlier values (`-Z ui-testing=yes -Z ui-testing=no` == `-Z ui-testing=no`), so it can be set in a hierarchical way, e.g. UI testing infra may enable it by default with specific tests being able to opt-out.
This way we can remove the special opt-out support from `compiletest`.
Inspired by https://github.com/rust-lang/rust/pull/67709.
it uses normalize-stderr-test because not all targets hit the same OS error number nor message ...
... and ignores tidy since I dont know how to make the normalize line shorter ...
and has effectively a no-op for its error-pattern because the targets' error
messages are so wildly different (and the error-pattern check occurs *before*
stderr normalization.)
