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.
