inmates: x86: discover and activate SSE/AVX
Recent gcc versions emit SSE instructions for 32-bit inmates (e.g., in
hex2str or cmdline_parse routines). Inmates aren't able to execute those
instructions as SSE is not enabled and will crash.
Enabling SSE is the same code for 32 and 64 bit x86 and straight
forward: Lookup SSE/AVX availability via cpuid and set according bits in
control registers.
Simply call the routine before calling the actual C entry point.

Log Message:
-----------
inmates: introduce test.h and test.c
MMIO access tests use the same test pattern. Let's share the code.
Later, we will also reuse it for the SSE test.

inmates: x86: Add SSE/AVX test inmate
Depending on availability, this inmates executes some SSE/AVX
instructions, compares the result against an expected result and exits.
