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.

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

The new testsuite is much more comprehensive, so remove the old one;
it is also buggy (the pinsrw test uses incorrect constraints, with =
instead of +, and the golden output for the fxsave tests differs depending
on how the C library uses SSE and AVX instructions).
