* config/epiphany/epiphany.c (epiphany_rtx_costs): Check for
        code == SET rather than outer_code == SET, to account for
        asymmetric calling patterns between combine and postreload.
        * (TARGET_MAX_ANCHOR_OFFSET, TARGET_MIN_ANCHOR_OFFSET): For
        optimize_size, reduce range to range for short SImode loads/stores.
        * gcc.target/epiphany/t1068-2.c: Adjust count to what is possible
        whilst move2add is stumped by flag clobbers.
