c7daba316e Re-add #![feature(target_feature_11)] 
We removed this in 307c42fbf4bdfdda2c46fdc1d330cc61d96b5182, but the
stabilization was reverted in https://github.com/rust-lang/rust/pull/108654.

According to google/cpu_features, IsProcessorFeaturePresent(PF_ARM_VFP_32_REGISTERS_AVAILABLE)
returns whether fp is available.

a9681a2ca6 Merge core_arch/tests/cpu-detection.rs to std_detect/tests/cpu-detection.rs 
Except for the recently added `x86_deprecated` test,
`core_arch/tests/cpu-detection.rs` is a subset of
`std_detect/tests/cpu-detection.rs`.

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.

6e5b949ee7 Check and pass the ACLE licence on to generated tests. 
The generated tests are transient, and aren't committed, so this is
primarily a safety check.

262d7c77bf Don't declare f16c_target_feature. 
f16c_target_feature was recently stabilised.

This fixes a warning that results in a CI failure (due to `-D
stable-features`) with current nightly Rust.

665e33f3be Match Neon test features to their intrinsics. 
The tests can run if and only if the target_features for the
corresponding intrinsics are detected at run-time, so make sure that the
tests have an appropriate `simd_test()`.

This fixes some failures due to tests running when they shouldn't. For
example, some tests would fail on hardware that lacks "fcma".

f966d451b5 Decouple TargetFeature strings. 
"arm" and "aarch64" support different sets of `target_feature` and
`simd_test` arguments, and for "arm", the set of features that can be
dynamically detected is different again. Restructure the generator code
to allow this to be expressed accurately (in future patches).

This implementation preserves the way that target features are specified
for shared intrinsics, because this has an impact on the generated
documentation. In particular, rustdoc cannot look inside
`cfg_attr(target_arch = ...)` tests, so we use unconditional
`target_feature` attributes where possible.
