Jason A. Donenfeld d127b15e38 UPSTREAM: crypto: x86/poly1305 - wire up faster implementations for kernel 
These x86_64 vectorized implementations support AVX, AVX-2, and AVX512F.
The AVX-512F implementation is disabled on Skylake, due to throttling,
but it is quite fast on >= Cannonlake.

On the left is cycle counts on a Core i7 6700HQ using the AVX-2
codepath, comparing this implementation ("new") to the implementation in
the current crypto api ("old"). On the right are benchmarks on a Xeon
Gold 5120 using the AVX-512 codepath. The new implementation is faster
on all benchmarks.

        AVX-2                  AVX-512

This commit wires in the prior implementation from Andy, and makes the
following changes to be suitable for kernel land.

  - Some cosmetic and structural changes, like renaming labels to
    .Lname, constants, and other Linux conventions, as well as making
    the code easy for us to maintain moving forward.

  - CPU feature checking is done in C by the glue code.

  - We avoid jumping into the middle of functions, to appease objtool,
    and instead parameterize shared code.

  - We maintain frame pointers so that stack traces make sense.

  - We remove the dependency on the perl xlate code, which transforms
    the output into things that assemblers we don't care about use.

Importantly, none of our changes affect the arithmetic or core code, but
just involve the differing environment of kernel space.
