77e786bb95 target/arm: Use correct output type for gvec_sdot_*_b 
The signed dot product routines produce a signed result.
Since we use -fwrapv, there is no functional change.

In addition, use the same vector generator interface for AdvSIMD.
This fixes a bug in which the AdvSIMD insn failed to clear the
high bits of the SVE register.
