simd-runtime-check-x64
This is a (nightly-only) library that provides an check at runtime to see if various SIMD features are supported.
The code has been taken from parched/runtime-target-feature-rs, see
https://github.com/parched/runtime-target-feature-rs/blob/master/rt/src/x86.rs
I have only seperated it into a crate because the runtime-target-feature-rs
crate didn't provide me with enough control to actually choose between
SIMD and non-SIMD versions of functions at runtime.
