[PATCH] Remove XFAIL for detecting dot-product pattern in vect-reduc-dot-s8b.c

[Richard Biener]

With the change to vect_reassociating_reduction_p this pattern will
always match (application is still conditional on uarch availability),
so remove the XFAIL.

Tested on x86_64-linux and aarch64-linux, pushed.

        dot-prod pattern detection.
