e54a6d71bf Improve feature detect for combined aarch64 features 
LLVM's `ssbs` and `mte` target_features represent two Arm features.
Linux's HWCAP also represents the same two features, so this is just a
documentation update.

LLVM's `ras` target_feature represents two Arm features - FEAT_RAS and FEAT_RASv1p1. There is no runtime detection for this, so this is a no-op in stdarch.

LLVM's `aes` feature covers both `FEAT_AES` and `FEAT_PMULL`, but Linux
exposes seperate feature bits. This patch makes the `aes` target_feature
correctly shortcut runtime `pmull` detection and also makes the `aes`
feature check for `pmull` at runtime to bring it in line with the
target_feature behaviour. In practice I think this makes the two runtime
features identical since the ID_AA64ISAR0_EL1 register does not allow
for PMULL without AES.

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`

e9d18c6b18 std_detect: Workaround Exynos 9810 bug on aarch64 Android 
Samsung Exynos 9810 has a bug that big and little cores have different
ISAs. And on older Android (pre-9), the kernel incorrectly reports
that features available only on some cores are available on all cores.
