commit 4eb4017ff1ca980e2ff8f78a21efd10f21f89c14
Author: Richard Biener <rguenther@suse.de>
Date:   Fri Sep 29 14:34:33 2023 +0200

    Properly reject SLP gather with builtin decl
    
    The builtin decl path for gather load vectorization doesn't implement
    SLP (PR111131).  Check that instead of ICEing.
    
            * tree-vect-stmts.cc (vectorizable_load): Reject SLP gather
            with builtin decl vectorization.
