    Fix PR94443 with gsi_insert_seq_before [PR94443]

    This patch is to fix the stupid mistake by using
    gsi_insert_seq_before instead of gsi_insert_before.

    BTW, the regression testing on one x86_64 machine from CFarm is
    unable to reveal it (I guess due to native arch sandybridge?), so I
    specified additional option -march=znver2 and verified the coverage.

    Bootstrapped/regtested on powerpc64le-linux-gnu (P9) and
    x86_64-pc-linux-gnu, also verified the fail cases in related PRs.

    Backport from mainline.
