rustbuild: Remove ThinLTO-related configuration

This commit removes some ThinLTO/codegen unit cruft primarily only needed during
the initial phase where we were adding ThinLTO support to rustc itself. The
current bootstrap compiler knows about ThinLTO and has it enabled by default for
multi-CGU builds which are also enabled by default. One CGU builds (aka
disabling ThinLTO) can be achieved by configuring the number of codegen units to
1 for a particular builds.

This also changes the defaults for our dist builders to go back to multiple
CGUs. Unfortunately we're seriously bleeding for cycle time on the bots right
now so we need to recover any time we can.

Rollup merge of #48706 - ehuss:main-not-found-in-crate, r=estebank
Add crate name to "main function not found" error message.

Fixes #44798 and rust-lang/cargo#4948.

I was wondering if it might be cleaner to update the ui tests to add a simple `fn main() {}` for the unrelated tests.  Let me know if you would prefer that.

Stabilise feature(never_type). Introduce feature(exhaustive_patterns)

This stabilizes `!`, removing the feature gate as well as the old defaulting-to-`()` behavior. The pattern exhaustiveness checks which were covered by `feature(never_type)` have been moved behind a new `feature(exhaustive_patterns)` gate.

Rollup merge of #48874 - jcowgill:mips-features, r=sanxiyn
bump mipsel isa leval and enable fpxx

This PR:
* Bumps the default ISA level of the mipsel targets to `mips32r2`. The big endian mips targets are already built with `mips32r2`. This is the usual baseline for the MIPS ISA these days used by other projects, although it does drop support for the 4K processor (which was the only processor released with mips32 r1). Debian no longer supports pre-R2 processors. Using R2 also improves code generation in FPXX in certain circumstances.
* Enables the FPXX floating point ABI[1] on 32-bit hard-float targets by default. This ABI adds some extra restrictions to the existing ABI which allows code to run on the two main floating point modes found on MIPS (FR0 and FR1) and remains compatible with the FR32 ABI currently in use. All code within an executable (including all shared libraries) must be compiled with FPXX/FP64 to be able to use MSA on 32-bit MIPS.
* Enables the "nooddspreg" feature with FPXX. This feature is usually enabled whenever FPXX is. It also helps workaround some issues on Loongson processors. I'm hoping this will fix some test failures mentioned in #39013.
* Adds the `fp64` feature to the MIPS whitelist. This feature must be enabled to use MSA on 32-bit MIPS, otherwise LLVM will complain.

tweak code fences in the rustdoc book

You can stack backticks to create "big code fences" if you're documenting some markdown and need to have code fences inside your code fences. This is especially important in this spot in the Rustdoc Book, because we're showing that using no language specifier on your code blocks is interpreted as using `rust`, but the code blocks here lose their code fences!

Rollup merge of #48765 - Phlosioneer:10234-wall-help-message, r=estebank
Add info message for -Wall command

Users coming from other languages (namely C and C++) often expect
to use a -Wall flag. Rustc doesn't support that, and previously it
simply printed that it didn't recognize the "all" lint.

This change makes rustc print out a help message, explaining:
- Why there is no -Wall flag
- How to view all the available warnings
- Point out that the most commonly used warning is -Wunused
- Instead of using a command-line flag, the user should consider
  a !#[warn(unused)] directive in the root of their crate.

I tried to keep the language consistent with the other usage help. Comment if I should change anything.

closes #10234, if accepted.

Remove syntax and syntax_pos thread locals

This moves `syntax` and `syntax_pos` globals into a struct which are pointed to by thread locals. Most of the changes here are indentation changes in test. It would probably be a good idea to ignore whitespace changes while reviewing. Some indentation is unchanged to avoid merge conflicts.
