The SVE masked load and store intrinsics introduced in D76688 <https://reviews.llvm.org/D76688> rely on
common llvm.masked.load/store nodes. This patch creates new ISD nodes
for LD1(S) & ST1 to remove this dependency.

Additionally, this adds support for sign & zero extending
loads and truncating stores.
