Migrate the x86_64 implementation of POLYVAL into lib/crypto/, wiring it up to the POLYVAL library interface. This makes the POLYVAL library be properly optimized on x86_64. This drops the x86_64 optimizations of polyval in the crypto_shash API. That's fine, since polyval will be removed from crypto_shash entirely since it is unneeded there. But even if it comes back, the crypto_shash API could just be implemented on top of the library API, as usual. Adjust the names and prototypes of the assembly functions to align more closely with the rest of the library code. Also replace a movaps instruction with movups to remove the assumption that the key struct is 16-byte aligned. Users can still align the key if they want (and at least in this case, movups is just as fast as movaps), but it's inconvenient to require it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
