    tree-optimization/116610 - wrong SLP induction bias for mask peeling

    The following fixes a mistake when applying the bias for peeling via
    masking to the inital value of SLP inductions.

    This resolves gcc.target/aarch64/sve/peel_ind_1.c (a scan-assembler
    only unfortunately) when forcing single-lane SLP for it.

            * tree-vect-loop.cc (vectorizable_induction): Use MINUS_EXPR
            to apply a mask peeling adjustment.
