2020-08-28target/arm: Merge helper_sve_clr_* and helper_sve_movz_*Richard Henderson
The existing clr functions have only one vector argument, and so can only clear in place. The existing movz functions have two vector arguments, and so can clear while moving. Merge them, with a flag that controls the sense of active vs inactive elements being cleared.

2020-06-26target/arm: Add mte helpers for sve scatter/gather memory opsRichard Henderson
Because the elements are non-sequential, we cannot eliminate many tests straight away like we can for sequential operations. But we often have the PTE details handy, so we can test for Tagged.

2020-02-21target/arm: Convert PMULL.8 to gvecRichard Henderson
We still need two different helpers, since NEON and SVE2 get the inputs from different locations within the source vector. However, we can convert both to the same internal form for computation. The sve2 helper is not used yet, but adding it with this patch helps illustrate why the neon changes are helpful.
