Fix ordering of auto-generated trait bounds in rustdoc output
While the order of the where clauses was deterministic, the
ordering of bounds and lifetimes was not. This made the order flip-
flop randomly when new traits and impls were added to libstd.
This PR makes the ordering of bounds and lifetimes deterministic,
and re-enables the test that was causing the issue.
Fixes #49123

Stabilize slice patterns without `..`
And merge `feature(advanced_slice_patterns)` into `feature(slice_patterns)`.
The detailed description can be found in https://github.com/rust-lang/rust/issues/48836.
Slice patterns were unstable for long time since before 1.0 due to many bugs in the implementation, now this stabilization is possible primarily due to work of @arielb1 who [wrote the new MIR-based implementation of slice patterns](https://github.com/rust-lang/rust/pull/32202) and @mikhail-m1 who [fixed one remaining class of codegen issues](https://github.com/rust-lang/rust/pull/47926).

Suggest removing `&`s
This implements the error message discussed in #47744.
We check whether removing each `&` yields a type that satisfies the requested obligation.
Also, it was created a new `NodeId` field in `ObligationCause` in order to iterate through the `&`s. The way it's implemented now, it iterates through the obligation snippet and counts the number of `&`.

Try to reduce amount of time on the asmjs builder
This PR has two commits for two separate strategies:
* First it disables optimizations for all tests, hopefully saving time by not optimizing the test code. This caused a number of run-pass tests to fail which are switched to being ignored here.
* Next it disables a number of test suites which aren't asm.js specific and already run elsewhere

- `span_suggestion` changed to `span_suggestion_short`;
- `Span` used changed to contain only `&` refs;
- Tests passing.

syntax: Make imports in AST closer to the source and cleanup their parsing

syntax: Make `_` a reserved identifier
Why:
- Lexically `_` is an identifier.
- Internally it makes implementation of `use Trait as _;` (https://github.com/rust-lang/rust/issues/48216) and some other things cleaner.
- We prevent the externally observable effect of `_` being accepted by macros expecting `ident` by treating `_` specially in the `ident` matcher:
```rust
macro_rules! m {
($i: ident) => { let $i = 10; }
}
m!(_); // Still an error
```

Checks for unknown attributes before aborting due to unresolved macros
Fixes #49074
The ``attribute `...` is currently unknown to the compiler`` error was not shown if there are any unresolved macros, which might be caused by mistyped `macro_use`.

add intrinsics for portable packed simd vector reductions
Adds the following portable vector reduction intrinsics:
* fn simd_reduce_add<T, U>(x: T) -> U;
* fn simd_reduce_mul<T, U>(x: T) -> U;
* fn simd_reduce_min<T, U>(x: T) -> U;
* fn simd_reduce_max<T, U>(x: T) -> U;
* fn simd_reduce_and<T, U>(x: T) -> U;
* fn simd_reduce_or<T, U>(x: T) -> U;
* fn simd_reduce_xor<T, U>(x: T) -> U;
I've also added:
* fn simd_reduce_all<T>(x: T) -> bool;
* fn simd_reduce_any<T>(x: T) -> bool;
These produce better code that what we are currently producing in `stdsimd`, but the code is still not optimal due to this LLVM bug: https://bugs.llvm.org/show_bug.cgi?id=36702

resolve `'_` in `dyn Trait` just like ordinary elision

Since all tests are compiled with LTO effectively in Emscripten this commit
disables optimizations to hopefully squeeze some more time out of the CI
builders.

check stability of macro invocations
I haven't implemented tests yet but this should be a pretty solid prototype. I think as-implemented it will also stability-check macro invocations in the same crate, dunno if we want that or not.
I don't know if we want this to go through `rustc::middle::stability` or not, considering the information there wouldn't be available at the time of macro expansion (even for external crates, right?).
