Extend the support to memory operands, and skip MMX instructions that
were introduced in SSE times, because they are now covered in test-mmx.

Adjust the test-avx.py generator to produce tests specifically for
MMX and 3DNow. Using a separate generator introduces some code
duplication, but is a simpler approach because of test-avx's extra
complexity to support 3- and 4-operand AVX instructions.
If needed, a common library can be introduced later.
While at it, for consistency move all the -cpu max rules to the
same place.

Tests for correct operation of most x86-64 SSE instructions.
It should cover all combinations of overlapping register and memory
operands on a set of random-ish data.
Results are bit-identical to an Intel i5-8500, with the exception of
the RCPSS and RSQRT approximations where the real CPU gives less accurate
results (the Intel spec allows relative errors up to 1.5 * 2^-12)
