implement more SIMD intrinsics

Requires https://github.com/rust-lang/rust/pull/94681

With this, the cast, i32_ops, and f32_ops test suites of portable-simd pass. :)

3854a76ace Auto merge of #1970 - asquared31415:open_unix_varargs, r=RalfJung 
Allow varargs for libc::open when it is allowed by the second argument

This PR allows `libc::open` to be called using two or three arguments as defined in https://man7.org/linux/man-pages/man2/open.2.html

The presence of the third argument depends on the value of the second argument.  If the second argument dictates that the third argument is *required* miri will emit an error if the argument is missing.  If the second argument does *not* require a third argument, then the argument is ignored and passed as 0 internally (it would be ignored by libc anyway)

Only print the pruning note if the trace was definitely pruned

Per https://github.com/rust-lang/miri/pull/1987#discussion_r815337994

The only problem with this is that it looks like we can't emit the note about `-Zmiri-backtrace=full` if we also emit a tag-tracking diagnostic. The final note about the setting simply doesn't appear on the final error if it is printed before. I feel like we're running up against some diagnostic deduplication logic?
