This patch series adds support for i386 and x86_64 architectures to
RISU. Notably, vector registers (SSE, AVX, AVX-512) are supported for
verification of the apprentice. This is V2 of the series posted in
[1].
I decided not to drop the register definitions from the second patch
as suggested by Alex Bennée [4], but replaced them in the fourth patch
instead. This keeps the second and third patches code-motion only.
I wasn't 100% sure how to acknowledge Richard's contributions in some
of the patches, and eventually decided to include a Suggested-by:
line. Let me know if that's (not) acceptable.

Changes in V2:
- included Richard Henderson's fix-ups [2] and vector register
support [3]
- replaced the magic numbers for XSAVE feature sets with symbolic
constants
- symbolic names ("sse", "avx", "avx512") as well as numbers are
accepted for the parameter --xfeatures
