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.
We have SIMD.float32x4.notEqual. Please add a comment that we should wire that up.
