GNURX toolchain generates incorrect opcode for "mov.b #0xff, [r0]" instruction.

Hi Vinay,

> Below patch fixes the issue reported. This is verified using following testcase.

Great - please could you add this testcase to the patch as a new entry in 
gas/testsuite/gas/rx ?  I suggest that you call the source file pr19665.s and the
test control file pr19665.d.  Then just add a line "run_dump_test "pr19665" to the
end of rx.exp.

Really ?  Because when I regression tested it I saw a new gas testsuite failure:

  regexp_diff match failure
  regexp "^ [0-9a-f]+:	3c 00 00                mov\.b	#0, 0\[r0\]$"
