slightly extend triagebot PR creation message
Remove implementation of LLVM SIMD intrinsics that are not needed anymore
This allows getting rid of all the argument mangling hacks as well as
the exported_non_generic_symbols override hack by doing cargo build
instead of cargo check. This is also a prerequisite for using native jit
mode support in miri that I hope to add to rustc in the future to be
used with cg_clif too.
./miri run: verbose by default, add flag to be quiet

Make pthread and other "native" synchronization objects more resilient
In unit tests, writes to stderr that don't use `eprint!` or `eprintln!` will
not be captured, and instead interfere with test harness output, making it
unreadable.
mgca: Finish implementation of `#[type_const]`

tracking issue: rust-lang#132980
fixes rust-lang#140729
fixes rust-lang#140860

- **Fix `#[type_const]` attribute placement validation**
- **Perform WF-checking on type_const RHS's**
- **Check type_const type is ConstParamTy_ and that RHS matches it**
- **Check that impls of `#[type_const]` consts also have the attr**

bootstrap: Render doctest timing reports as text, not JSON

These doctest timing reports were added to libtest/rustdoc in rust-lang#144909, but bootstrap's custom test-output renderer wasn't taught about them, so they were being printed as raw JSON instead.

Before:
```text
{ "type": "report", "total_time": 0.738403958, "compilation_time": 0.731513292 }
```

After:
```text
all doctests ran in 0.73s; merged doctests compilation took 0.72s
```

tidy: Don't bypass stderr output capture in unit tests

In unit tests, writes to stderr that don't use `eprint!` or `eprintln!` will not be captured, and instead interfere with test harness output, making it unreadable.
