[PATCH] Adjust assert in vect_build_slp_tree_2

[Richard Biener]

The assert in SLP discovery when we handle masked operations is
confusingly wide - all gather variants should be catched by
the earlier STMT_VINFO_GATHER_SCATTER_P.

Bootstrap and regtest running on x86_64-unknown-linux-gnu.

        * tree-vect-slp.cc (vect_build_slp_tree_2): Only expect
        IFN_MASK_LOAD for masked loads that are not
        STMT_VINFO_GATHER_SCATTER_P.
