Lint overflowing integer casts in const prop

This extends the invalid cases we catch in const prop to include
overflowing integer casts using the same machinery as the overflowing
binary and unary operation logic.

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.

Rollup merge of #67748 - MaskRay:frame-pointer, r=rkruppe 
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.

Rollup merge of #67744 - Centril:reduce-diversity, r=petrochenkov 
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.

Rollup merge of #67574 - Centril:librustc_lowering, r=Mark-Simulacrum 
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).

Rollup merge of #67735 - petrochenkov:uibool, r=Mark-Simulacrum 
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`.

Rollup merge of #67430 - tspiteri:minus-inf, r=Dylan-DPC 
doc: minus (U+2212) instead of dash (U+002D) for negative infinity

The documentation for [`f32::NEG_INFINITY`](https://doc.rust-lang.org/std/f32/constant.NEG_INFINITY.html) contains “-∞” with a dash instead of a minus sign, “−∞” with a proper minus sign looks better with the used Source Serif Pro font. Similarly for [`f64::NEG_INFINITY`](https://doc.rust-lang.org/std/f64/constant.NEG_INFINITY.html).
