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`

d1df958a32 Remove the auxv dev dependency. 
It hasn't been used since roughly 2018. The latest published version of
auxv has a less common license and doesn't specify any license in it's
Cargo.toml file.

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.

39f73ac0b3 Allow internal use of stdsimd from detect_feature 
This allows using feature detection macros, without placing a
requirement of enabled stdsimd feature gate from end users.

A follow-up to changes from #1311, which introduced the new macro.
