Changelog:
v0:
* Rename GEN_VXFORM_300_EXT1 to GEN_VXFORM_300_EO.
* Rename GEN_VXFORM_DUAL1 to GEN_VXFORM_DUAL_INV.
* Remove undef GEN_VXFORM_DUAL1.
v1:
* Correct SPLAT and handle src = dest for vinsert and vextract.
* Correct typecast for vctz.
* Computation of index rearranged for vpermr.
* Assignment of perm moved out of inner loop in vbpermd.
v2:
* Check splat in transate code for vinsert and vextract.
* Use memcpy for vinsert and vextract.
* Handle src = dest for vbpermd.
v3:
* vinsert - Use memmove, Rename splat and use index with reference to u8.
* vextract - Use memmove, Rename splat and use index with reference to u8.
* vbpermd - Remove variable perm and use EXTRACT_BIT.
v4:
* vextract - Assign result register to zero.
