[PATCH] Fix typo in expander trunc2 [AVX512]

[Hongtao Liu via Gcc-patches]

This patch to is fix uppercase of mode in trunc<mode><pmov_dst_3>2, it
should be lowercase for standard pattern name.

  Bootstrap is ok, regression test on i386/x86-64 backend is ok.

gcc/ChangeLog:
        * config/i386/sse.md (pmov_dst_3_lower): New mode attribute.
        (trunc<mode><pmov_dst_3_lower>2): Refine from
        trunc<mode><pmov_dst_3>2.

gcc/testsuite
        * gcc.target/i386/pr92658-avx512bw-trunc.c: Adjust testcase.
