* gimple-ssa-strength-reduction.c (create_add_on_incoming_edge):
Don't allow a MINUS_EXPR for pointer arithmetic for either known
or unknown strides.
(record_increment): Increments of -1 for unknown strides just use
a multiply initializer like other negative values.
(analyze_increments): Remove stopgap solution for -1 increment
applied to pointer arithmetic.
