ppc: Document the -mfuture and -Mfuture options and make them usable
The -mfuture and -Mfuture options which are used for adding potential new ISA instructions were not documented. They also lacked a bitmask so new instructions could not be enabled by those options. Fixed. binutils/ * doc/binutils.texi: Document -Mfuture. gas/ * config/tc-ppc.c: Document -mfuture * doc/c-ppc.texi: Likewise. include/ * opcode/ppc.h (PPC_OPCODE_FUTURE): Define. opcodes/ * ppc-dis.c (ppc_opts) <future>: Use it. * ppc-opc.c (FUTURE): Define.
