Make repr(packed) vectors work with SIMD intrinsics

In #117116 I fixed `#[repr(packed, simd)]` by doing the expected thing and removing padding from the layout.  This should be the last step in providing a solution to rust-lang/portable-simd#319

e9ef8e1efa Rollup merge of #122935 - RalfJung:with-exposed-provenance, r=Amanieu 
rename ptr::from_exposed_addr -> ptr::with_exposed_provenance

As discussed on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/136281-t-opsem/topic/To.20expose.20or.20not.20to.20expose/near/427757066).

The old name, `from_exposed_addr`, makes little sense as it's not the address that is exposed, it's the provenance. (`ptr.expose_addr()` stays unchanged as we haven't found a better option yet. The intended interpretation is "expose the provenance and return the address".)

The new name nicely matches `ptr::without_provenance`.

Detect when the constant expression isn't `usize` and suggest casting:

6a4dd19ade Rollup merge of #122287 - RalfJung:simd-static-assert, r=pnkfelix 
add test ensuring simd codegen checks don't run when a static assertion failed

stdarch relies on this to ensure that SIMD indices are in bounds.

I would love to know why this works, but I can't figure out where codegen decides to not codegen a function if a required-const does not evaluate. `@oli-obk` `@bjorn3` do you have any idea?

cf6d6050f7 Update test directives for wasm32-wasip1 
* The WASI targets deal with the `main` symbol a bit differently than
  native so some `codegen` and `assembly` tests have been ignored.
* All `ignore-emscripten` directives have been updated to
  `ignore-wasm32` to be more clear that all wasm targets are ignored and
  it's not just Emscripten.
* Most `ignore-wasm32-bare` directives are now gone.
* Some ignore directives for wasm were switched to `needs-unwind`
  instead.
* Many `ignore-wasm32*` directives are removed as the tests work with
  WASI as opposed to `wasm32-unknown-unknown`.

52dba5ffe7 Auto merge of #121225 - RalfJung:simd-extract-insert-const-idx, r=oli-obk,Amanieu 
require simd_insert, simd_extract indices to be constants

As discussed in https://github.com/rust-lang/rust/issues/77477 (see in particular [here](https://github.com/rust-lang/rust/issues/77477#issuecomment-703149102)). This PR doesn't touch codegen yet -- the first step is to ensure that the indices are always constants; the second step is to then make use of this fact in backends.

Blocked on https://github.com/rust-lang/stdarch/pull/1530 propagating to the rustc repo.
