tests/tcg: i386: add SSE tests
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)
