…ive support

And retire the old `only-debug` directive which was ambiguous and only
for std debug assertions.
And rename local variables and field names in bootstrap from
`debug_assertions{,_std}` -> `{rustc,std}-debug-assertions` to avoid
confusion where applicable.
Add functions to retrieve function definitions and static items from
all crates (local and external).

For external crates, add a query to retrieve the number of defs in a
foreign crate.
Set "symbol name" in raw-dylib import libraries to the decorated name

`windows-rs` received a bug report that mixing raw-dylib generated and the Windows SDK import libraries was causing linker failures: <microsoft/windows-rs#3285>

The root cause turned out to be rust-lang#124958, that is we are not including the decorated name in the import library and so the import name type is also not being correctly set.

This change modifies the generation of import libraries to set the "symbol name" to the fully decorated name and correctly marks the import as being data vs function.

Note that this also required some changes to how the symbol is named within Rust: for MSVC we now need to use the decorated name but for MinGW we still need to use partially decorated (or undecorated) name.

Fixes rust-lang#124958

Passing i686 MSVC and MinGW build: <https://github.com/rust-lang/rust/actions/runs/11000433888?pr=130586>

Add `{ignore,needs}-{rustc,std}-debug-assertions` directive support

Add `{ignore,needs}-{rustc,std}-debug-assertions` compiletest directives and retire the old `{ignore,only}-debug` directives. The old `{ignore,only}-debug` directives were ambiguous because you could have std built with debug assertions but rustc not built with debug assertions or vice versa. If we want to support the use case of controlling test run based on if rustc was built with debug assertions, then having `{ignore,only}-debug` will be very confusing.

Closes rust-lang#123987.

Fix rust-lang#131977 parens mangled in shared mut static lint suggestion

Resolves rust-lang#131977 for static mut references after discussion with
Esteban & Jieyou on [t-compiler/help](https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/linting.20with.20parens.20in.20the.20HIR).

This doesn't do anything to change the underlying issue if there are other expressions that generate lint suggestions which need to be applied within parentheses.

[StableMIR] API to retrieve definitions from crates

Add functions to retrieve function definitions and static items from all crates (local and external).

For external crates, we're still missing items from trait implementation and primitives.

r? ````@compiler-errors:```` Do you know what is the best way to retrieve the associated items for primitives and trait implementations for external crates? Thanks!

core: move intrinsics.rs into intrinsics folder

This makes the rustbot notification we have set up for this folder in `triagebot.toml` actually work. Also IMO it makes more sense to have it all in one folder.

Compile `test_num_f128` conditionally on `reliable_f128_math` config

With rust-lang#132434 merged, our internal SGX CI started failing with:
```

```
This originated from the `test_num_f128` test not having the required conditional compilation. This PR fixes that issue.

bootstrap: Print better message if lock pid isn't available

Not actually sure why, but sometimes the PID isn't available so we print
```
WARNING: build directory locked by process , waiting for lock
```
This makes the message a bit nicer in this case
