Fix the disassmbly of SH instructions which have an unsigned 8-bit immediate operand.
PR 22699
opcodes * sh-opc.h (IMM0_8): Replace with IMM0_8S and IMM0_8U. Use
IMM0_8S for arithmetic insns and IMM0_8U for logical insns.
* sh-dis.c (print_insn_sh): Change IMM0_8 case to IMM0_8S and add
IMM0_8U case.
gas * config/tc-sh.c (build_Mytes): Change operand type IMM0_8 to
IMM0_8S and add support for IMM0_8U.
* testsuite/gas/sh/sh4a.s: Add test of a logical insn using an
unsigned 8-bit immediate.
* testsuite/gas/sh/sh4a.d: Extended expected disassembly.
