168479a4a5 std_detect: Add pauth-lr aarch64 target feature 
Add feature detection for aarch64 FEAT_PAuth_LR.
There is currently no Linux cpuinfo support so the OS-specific lines are
commented out.

485ded6369 std_detect: Add sme-b16b16 as an explicit aarch64 target feature 
LLVM 20 split out what used to be called b16b16 and correspond to aarch64
FEAT_SVE_B16B16 into sve-b16b16 and sme-b16b16.
Add sme-b16b16 as an explicit feature and update the detection accordingly.

8a511191a0 Enable feature detection on all Apple/Darwin targets 
Tested in the simulator and on the device I had lying around, a 1st
generation iPad Mini (which isn't Aarch64, but shows that the
`sysctlbyname` calls still work even there, even if they return false).

`sysctlbyname` _should_ be safe to use without causing rejections from
the app store, as its usage is documented in:
https://developer.apple.com/documentation/kernel/1387446-sysctlbyname/determining_instruction_set_characteristics

Also, the standard library will use these soon anyhow, so this shouldn't
affect the situation:

ef538bc614 std_detect: Add aarch64/linux/LLVM SME features 
Add detection for SME features supported by LLVM and the Linux Kernel.
Include commented-out hwcap fields for features supported by Linux but not by LLVM.

This commit adds feature detection for the following features:

- FEAT_SME
- FEAT_SME_F16F16
- FEAT_SME_F64F64
- FEAT_SME_F8F16
- FEAT_SME_F8F32
- FEAT_SME_FA64
- FEAT_SME_I16I64
- FEAT_SME_LUTv2
- FEAT_SME2
- FEAT_SME2p1
- FEAT_SSVE_FP8DOT2
- FEAT_SSVE_FP8DOT4
- FEAT_SSVE_FP8FMA

Linux features: https://github.com/torvalds/linux/blob/master/arch/arm64/include/uapi/asm/hwcap.h
LLVM features: llvm-project/llvm/lib/Target/AArch64/AArch64.td

dfc5dfc8ef std_detect: Add aarch64/linux/LLVM features 
Add detection for various aarch64 CPU features already supported by LLVM and Linux.

This commit adds feature detection for the following features:

- FEAT_CSSC
- FEAT_ECV
- FEAT_FAMINMAX
- FEAT_FLAGM2
- FEAT_FP8
- FEAT_FP8DOT2
- FEAT_FP8DOT4
- FEAT_FP8FMA
- FEAT_HBC
- FEAT_LSE128
- FEAT_LUT
- FEAT_MOPS
- FEAT_LRCPC3
- FEAT_SVE_B16B16
- FEAT_SVE2p1
- FEAT_WFxT

It also adds feature detection for FEAT_FPMR. It is somewhat of a
special case because FPMR only exists as a feature in LLVM 18, it has
been removed from the LLVM upstream. On that account the intention is
for it to be detectable at runtime through stdarch but not have a
corresponding compile-time Rust target feature.

Linux features: https://github.com/torvalds/linux/blob/master/arch/arm64/include/uapi/asm/hwcap.h
LLVM features: llvm-project/llvm/lib/Target/AArch64/AArch64.td
