x86/lpc: implement a new Welch windowing function 
Old one was written with the assumption only even inputs would be given.
This very messy replacement supports even and odd inputs, and supports
AVX2 for extra speed. The buffers given are usually quite big (4k samples),
so the speedup is worth it.
The new SSE version is still faster than the old inline asm version by 33%.

Also checkasm is provided to make sure this monstrosity works.

This fixes some FATE tests.
