Rollup merge of #49077 - sinkuu:macro_use_typo, r=estebank 
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`.

Rollup merge of #48983 - gnzlbg:red, r=alexcrichton 
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

a7170b0412 Auto merge of #48524 - abonander:check-macro-stability, r=petrochenkov 
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?).

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.

Disallow &a..=b and box a..=b in pattern. 
They are disallowed because they have different precedence than
expressions. I assume parenthesis in pattern will be soon stabilized and
thus write that as suggestion directly.
