dd65ed38db Require prefix of instruction line to be the expected instruction 
`rsqrtps %xmm0,%xmm1` used to match `sqrtps` without leading `r`.

51c3295de1 Fix unused import: mem::transmute 
When building on aarch64, the following warning occurs.

```
warning: unused import: `mem::transmute`

cca9a86637 Add CRC32 detection to arm32 
armv8 has 32-bit mode, but it can use crc32 instruction sets even if 32-bit.

7c56404f1a Add #[rustc_args_required_const] to simd_shuffle 
Currently, these have to be special-cased in the promotion logic for rustc.

f3140f4b25 Factor out check_for 
All the os-specific code implements a `check_for` and a `detect_features`.

Move the always identical check_for in the mod.rs and use
`os::detect_features` there.

5bfd08cd65 Auto merge of #796 - Mark-Simulacrum:bootstrap-snap, r=gnzlbg 
Apply snap of bootstrap compiler in rust-lang/rust

FWIW, in the future we should try to avoid this as I'm assuming we'll break CI trying to land this here (and we can't swap bootstrap compilers in Rust until this lands).

c519f89682 Auto merge of #799 - gnzlbg:has_test, r=gnzlbg 
Verify that all intrinsics have a run-time test

Add a check to stdsimd-verify to check that all intrinsics have a run-time test. This is not the case right now, but we should at least not add intrinsics without tests.
