Disable all x64 SIMD tests, as some seem to be nondeterministic.

Browse Source 
We are seeing some repeated but nondeterministic failures of x64 SIMD
tests, as tracked in #2470. In order to err on the side of not
inadvertently breaking/blocking CI for others, we will disable all SIMD
tests for now while we investigate.
