Use movd,movq for i32/64 VectorExtract %x, 0x0 (#1439)

Browse source 
* 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. :(
