[PATCH v1 0/3] Support RVV register overlap for vwmulsu.vv

From: Pan Li <[email protected]>

Like v[sz]ext.vf8, we continue the support for vwmulsu.vv.

The below test suites are passed for this patch:
1. The rv64gcv fully regression tests.

Pan Li (3):
  RISC-V: Allow RVV register overlap for vwmulsu.vv
  RISC-V: Add test cases for vwmulsu.vv reg overlap
  RISC-V: Add more test cases for vwmulsu.vv
