MIPS16: Reassign `0' and `4' operand codes
Replace `0' and `4' operand codes with `.' and `F' respectively to free up the `0'-`4' consecutive range. No functional change. gas/ * config/tc-mips.c (mips16_macro_build): Replace `0' and `4' operand codes with `.' and `F' respectively. (mips16_macro): Likewise. include/ * opcode/mips.h: Replace `0' and `4' operand codes with `.' and `F' respectively. opcodes/ * mips16-opc.c (decode_mips16_operand): Replace `0' and `4' operand codes with `.' and `F' respectively. (mips16_opcodes): Likewise.
