Kerry McLaughlin 30eb603e95 [SVE][CodeGen] Legalisation of masked loads and stores
Summary:
This patch modifies IncrementMemoryAddress to use a vscale
when calculating the new address if the data type is scalable.

Also adds tablegen patterns which match an extract_subvector
of a legal predicate type with zip1/zip2 instructions
