60e9e3f1b0117a3aefd4a8047168f1c20f6c9013 s390x/tcg: Implement VECTOR LOAD TO BLOCK BOUNDARY
Very similar to LOAD COUNT TO BLOCK BOUNDARY, but instead of only
calculating, the actual vector is loaded. Use a temporary vector to
not modify the real vector on exceptions. Initialize that one to zero,
to not leak any data. Provide a fast path if we're loading a full
vector.
As we don't have gvec ool handlers for single vectors, just calculate
the vector address manually.
We can reuse the helper later on for VECTOR LOAD WITH LENGTH. In fact,
we are going to name it "vll" right from the beginning, because that's
a better match.
