Add missing ARM-v7A CRC intrinsics (#1515) 
* Move aarch64 crc into arm shared module

* Add missing 32-bit arm crc intrinsics

On 32-bit ARM, this intrinsic emits two instructions and splits its 64-bit input parameter between them.

786f28dd8b Stabilize Ratified RISC-V Target Features 
As shortly discussed on Zulip
(https://rust-lang.zulipchat.com/#narrow/stream/250483-t-compiler.2Frisc-v/topic/Stabilization.20of.20RISC-V.20Target.20Features/near/394793704), this commit stabilizes the ratified RISC-V instruction bases and extensions.

Specifically, this commit stabilizes the:
* Atomic Instructions (A) on v2.0
* Compressed Instructions (C) on v2.0
* Integer Multiplication and Division (M) on v2.0
* Bit Manipulations (B) on v1.0 listed as `zba`, `zbc`, `zbs`
* Scalar Cryptography (Zk) v1.0.1 listed as `zk`, `zkn`, `zknd`, `zkne`, `zknh`, `zkr`, `zks`, `zksed`, `zksh`, `zkt`, `zbkb`, `zbkc` `zkbx`

4fe088329c Work around CI failures for the ARM target 
These seem to have been introduced by recent LLVM changes.

* The instruction limit for vld*/vst* has been raised. This is not a
significant issue, it is only used for testing.
* vld*/vst* instructions are generated with overly strict alignments:
https://github.com/rust-lang/stdarch/issues/1217
* vtbl/vtbx instrinsics are failing intrinsic-test for unknown reasons.

05afebca4d Clean up intrinsic-test literals. 
- Ensure that C literals don't rely on undefined overflow behaviour.
- We don't need to use 'as' casts, so remove them.
- We weren't using allow(overflowing_literals), so remove it.
- Format FP bit values as hex.

This simplifies the test input initialisers in the generated files,
making them shorter and easier to debug.

1970299926 Remove unnecessary unsafety in intrinsic tests. 
This fixes "unnecessary `unsafe` block" warnings encountered when
building the generated rust_programs.

The only pattern that actually required `unsafe` was transmuting bit
patterns into floats. This patch uses the safe `from_bits` instead, but
because that isn't const, we have to make them local let-bound
variables.
