fa766fe954 Add #[cfg_attr(miri, ignore)] to tests of functions that cannot be supported by Miri 
This includes functions that use inline assemby or that do certains operations such as saving/restoring the processor state.

7f5fd0955a Disable NEON intrinsics on big-endian ARM 
These are currently broken because the order of elements inside
vectors is reversed on big-endian systems: the ARM ABI requires that
element 0 is located at the highest address of the vector type. However
LLVM intrinsics expect element 0 to be located at the lowest address.

See https://llvm.org/docs/BigEndianNEON.html and `arm_neon.h` in
Clang for more details.

Although this is a breaking change, this is acceptable for 2 reasons:
- big endian ARM targets are only tier 3.
- it is preferable to stop existing code from compiling than to let it
run and produce incorrect results.

45f28923ce Fix UB in _mm_movemask_ps, _mm_movemask_pd, _mm256_movemask_ps and _mm256_movemask_pd 
The `simd_bitmask` intrinsic requires each element to be all-1 or all-0, while the x86 functions only check for the highest bit.
