73996df629 Reset Formatter flags on exit from pad_integral 
This fixes a bug where after calling pad_integral with appropriate flags, the
fill and alignment flags would be set to '0' and 'Right' and left as such even
after exiting pad_integral, which meant that future calls on the same Formatter
would get incorrect flags reported.

This is quite difficult to observe in practice, as almost all formatting
implementations in practice don't call `Display::fmt` directly, but rather use
`write!` or a similar macro, which means that they cannot observe the effects of
the wrong flags (as `write!` creates a fresh Formatter instance). However, we
include a test case.

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`.

Inspired by https://github.com/rust-lang/rust/pull/67709.

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).

Rename some crates and modules in the frontend

Migrate from `syntax_*` naming scheme to `rustc_*`.
See https://github.com/rust-lang/rust/pull/65324#issuecomment-551103396 and several comments below.

Renamed crates:
`syntax_expand` -> `rustc_expand`
`syntax_pos` -> `rustc_span` ([motivation](https://github.com/rust-lang/rust/pull/65324#issuecomment-552173320))
`syntax_ext` -> `rustc_builtin_macros`

Also one module in resolve is renamed for consistency and to avoid tautology.
