[PATCH v1 0/2] Fix incorrect combine pattern for vwaddu/vwsubu wx

[pan2 . li]

From: Pan Li <pan2...@intel.com>

The vwaddu/vwsubu wx combine takes the any_extend by mistake, this
series would like to fix it by the zero_extend.

The below test suites are passed for this patch series.
* The rv64gcv fully regression test.
