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.

a49ca40768 riscv: P extension intrinsics for packed SIMD (part 1) 
Implement by inline assembly for now, uses `pure, nomem, nostack` for
all packed simd arithmetic instructions. Uses `inlateout` when it
requires using the same register for input and output, use `lateout`
for all output registers.

This commit also includes a rearrangement of shared risc-v architecture
module to improve documents. It also includes a doc test fix, gate sm3/4
and use explict sm3/4 instruction under rustc target feature.
