Merge patch series "target/riscv: some vector_helper.c cleanups"

Daniel Henrique Barboza <dbarboza@ventanamicro.com> says:

This is a re-send of patch 1, which is already reviewed, with a
follow-up that uses riscv_cpu_cfg() in the remaining of the file. This
was suggested by Weiwei Li in the "[PATCH 0/4] RISCVCPUConfig related
cleanups" review. Patch 1 makes the work of patch 2 easier since it
eliminated some uses of env_archcpu() we want to avoid.

* b4-shazam-merge:
  target/riscv/vector_helper.c: avoid env_archcpu() when reading RISCVCPUConfig
  target/riscv/vector_helper.c: create vext_set_tail_elems_1s()
