Use movd,movq for i32/64 VectorExtract %x, 0x0 (#1439)
* Use movd,movq for i32/64 VectorExtract %x, 0x0 * Increment PPTC interval version * Use else-if instead - Address gdkchan's feedback. - Clean up Debug.Assert calls * Inline `count` expression into Debug.Assert Apparently the CoreCLR JIT will not eliminate this. :(
