Fix display of RL78 MOVW instructions that use the stack pointer.
* rl78-decode.opc (rl78_decode_opcode): Add 's' operand to movw
instructions that can support stack pointer operations.
* rl78-decode.c: Regenerate.
* rl78-dis.c: Fix display of stack pointer in MOVW based
instructions.
* testsuite/gas/rl78/sp-relative-movw.s: New test.
* testsuite/gas/rl78/sp-relative-movw.d: Expected disassembly.
* testsuite/gas/rl78/rl78.exp: Run the new test.
