[RFC][SVE] Extend vector types to support SVE registers.
...* sizeof(ElementType) == 128bits) as legal, with the others promoted or spilt accordingly. Floating point and boolean vector MVTs are the exception whereby the smaller than usually legal types are legal and considered to contain unpacked data within a larger container. The type legalisation of:
nxv2i8 ADD(nxv2i8, nxv2i8)
results in:
nxv2i8 TRUNC(nxv2i64 ADD((ZERO_EXTEND MVT::nxv2i8), (ZERO_EXTEND MVT::nxv2i8)))
Much of the legalisation code is common to all targets and by introducing scalable vector MVTs they also apply to SVE as long as the "scalable" flag is preserved when transf...
