SSE1 test suite.

Adds a _failing_ test which refers to _each_ intrinsic provided by Intel Intrinsic reference in `xmmintrin.h`. Not to be merged yet , unless we skip the test from being run in the suite. The test passes if built and run natively with gcc or clang.
A more efficient implementation is _mm_cmpeq_ps(__a, __a) & __mm_cmpeq_ps(__b, __b). We should also consider adding "ord" comparisons to SIMD.js of course.
