    VECT: Support SLP for MASK_LEN_GATHER_LOAD with dummy mask

    This patch fixes following FAILs for RVV:
    FAIL: gcc.dg/vect/vect-gather-1.c -flto -ffat-lto-objects  scan-tree-dump
vect "Loop contains only SLP stmts"
    FAIL: gcc.dg/vect/vect-gather-1.c scan-tree-dump vect "Loop contains only
SLP stmts"

    Bootstrap on X86 and regtest passed.

    Ok for trunk ?

    gcc/ChangeLog:

            * tree-vect-slp.cc (vect_get_and_check_slp_defs): Support SLP for
dummy mask -1.
            * tree-vect-stmts.cc (vectorizable_load): Ditto.
