  -----------
  [CodeGen][SVE] Calculate correct type legalization for scalable vectors.

This patch updates TargetLoweringBase::computeRegisterProperties and
TargetLoweringBase::getTypeConversion to support scalable vectors,
and make the right calls on how to legalise them. These changes are required
to legalise both MVTs and EVTs.
