[S390] Fix disassembly of RX_URRD, SI_URD & PC-relative instructions.
The instructions with format RX_URRD and SI_URD and instructions with a PC relative operand are not disassembled correctly. For RX_URRD and SI_URD instructions find_insn sets opfrag to code[0]. The mask byte of these two formats is 0x00. table->opfrag will never be identical to (opfrag & opmask) and no matching instruction will be found. Set the mask byte to 0xff to actually check byte 0 against the table. For PC relative instructions the (unsigned) offset value needs to be casted to an signed integer so that negative branch offsets are handled correctly.
