ecc8d7ccb6 Use const {} for the immediate args of _mm*_cmp_* 
Rustc_codegen_cranelift requires immediates to already be constant in
MIR unlike LLVM which only needs them constant after optimizations.

31e17e39c2 Add AArch64 vrnd*_f64 Neon intrinsics. 
The LLVM intrinsic doesn't support float64x1_t, but the required
instruction is a scalar form (e.g. `frint32x <Dd>, <Dn>`), so we can
implement these using the scalar intrinsic.

Note that Clang does not support these intrinsics, so they aren't
covered by intrinsic-test. Additional validation is included in this
patch to ensure that we're selecting an instruction with the same
behaviour as the corresponding vector form (which all have
intrinsic-tests).

0459405ea9 Add more AArch64 vrnd intrinsics. 
LLVM can't select float64x1_t variants, but float64x2_t variants work.

1e15fa3f0a Add support for AArch64 i8mm *dot intrinsics.

product operations.

636476bcc1 Remove obscure & rarely used ARM intrinsics 
In almost all cases it is preferable to use the stable `asm!` instead of
calling these intrinsics.

This PR removes the following unstable intrinsics:
- `__breakpoint` Clang extension, not part of ACLE.
- `brk`: undocumented
- `_rev*`, `_clz*`, `_rbit*`: use methods on integer types instead
- `__ldrex`, `__strex`: deprecated in ACLE, hard to use correctly
- Register access API: API doesn't match ACLE, better to just use asm

Also considered for deletion, but not included in this PR:
- Barriers: `__isb`, `__dsb`, `__dmb`
- Hints: `__wfi`, `__wfe`, `__sev`, `__sevl`, `__yield`, `__nop`

I didn't include `__m512bh` since `__m128bh` is also unstable.
