f77bcc86b1 rustc: Remove soft-float from MIPS targets
Right now two MIPS targets in the compiler, `mips-unknown-linux-{gnu,musl}` both
generate object files using the soft-float ABI through LLVM by default. This is
also expressed as the `-C soft-float` codegen option and otherwise isn't used
for any other target in the compiler. This option was added quite some time ago
(back in #9617), and nowadays it's more appropriate to be done through a codegen
option.

This is motivated by #34743 which necessitated an upgrade in the CMake
installation on our bots which necessitated an upgrade in the Ubuntu version
which invalidated the MIPS compilers we were using. The new MIPS compilers
(coming from Debian I believe) all have hard float enabled by default and soft
float support not built in. This meant that we couldn't upgrade the bots
until #34841 landed because otherwise we would fail to compile C code as the
`-msoft-float` option wouldn't work.

Unfortunately, though, this means that once we upgrade the bots the C code we're
compiling will be compiled for hard float and the Rust code will be compiled
for soft float, a bad mismatch! This PR remedies the situation such that Rust
will compile with hard float as well.

If this lands it will likely produce broken nightlies for a day or two while we
get around to upgrading the bots because the current C toolchain only produces
soft-float binaries, and now rust will be hard-float. Hopefully, though, the
upgrade can go smoothly!

9c88898076 Auto merge of #34899 - michaelwoerister:always_internalize_symbols, r=eddyb
Run base::internalize_symbols() even for single-codegen-unit crates.

The initial linkage-assignment (especially for closures) is a conservative one that makes some symbols more visible than they need to be. While this is not a correctness problem, it does force the LLVM inliner to be more conservative too, which results in poor performance. Once translation is based solely on MIR, it will be easier to also make the initial linkage assignment a better fitting one. Until then `internalize_symbols()` does a good job of preventing most performance regressions.

This should solve the regressions reported in https://github.com/rust-lang/rust/issues/34891 and maybe also those in https://github.com/rust-lang/rust/issues/34831.

As a side-effect, this will also solve most of the problematic cases described in https://github.com/rust-lang/rust/issues/34793. Not reliably so, however. For that, we still need a solution like the one implement in https://github.com/rust-lang/rust/pull/34830.

macros: fix bug in `stmt` matchers

Today, `stmt` matchers stop too early when parsing expression statements that begin with non-braced macro invocations. For example,
```rust
fn main() {
    macro_rules! m { ($s:stmt;) => { $s } }
    id!(vec![].push(0););
    //^ Before this PR, the `stmt` matcher only consumes "vec![]", so this is an error.
    //| After this PR, the `stmt` matcher consumes "vec![].push(0)", so this compiles.
}
```
This change is backwards compatible due to the follow set for `stmt`.

Do not resolve inherent static methods from other crates prematurely

Under some specific circumstances paths like `Type::method` can be resolved early in rustc_resolve instead of type checker. `Type` must be defined in another crate, it should be an enum or a trait object (i.e. a type that acts as a "module" in resolve), and `method` should be an inherent static method.
As a result, such paths don't go through `resolve_ufcs`, may be resolved incorrectly and break some invariants in type checker. This patch removes special treatment of such methods.

The removed code was introduced in 2bd46e767c to fix a problem that no longer exists.

Simplify librustc_errors

This is part 2 of the error crate refactor, starting with #34403.

In this refactor, I focused on slimming down the error crate to fewer moving parts.  As such, I've removed quite a few parts and replaced the with simpler, straight-line code.  Specifically, this PR:

* Removes BasicEmitter
* Remove emit from emitter, leaving emit_struct
* Renames emit_struct to emit
* Removes CoreEmitter and focuses on a single Emitter
* Implements the latest changes to error format RFC (#1644)
* Removes (now-unused) code in emitter.rs and snippet.rs
* Moves more tests to the UI tester, removing some duplicate tests in the process

There is probably more that could be done with some additional refactoring, but this felt like it was getting to a good state.

llvm, rt: build using the Ninja generator if available

The Ninja generator generally builds much faster than make. It may also
be used on Windows to have a vast speed improvement over the Visual
Studio generators.

Currently hidden behind an `--enable-ninja` flag because it does not
obey the top-level `-j` or `-l` flags given to `make`.
