Remove ppc860, ppc750cl, ppc7450 insns from common ppc.

Browse Source 
Back in the day support for these processors was added, we probably
didn't want to waste PPC_OPCODE bits on minor variations.  I've had a
complaint that disassembly of mfspr/mtspr was wrong for power8.  This
patch fixes that problem.

Note that since -m860/-m850/-m821 are new gas options enabling the
mpc8xx specific mfspr/mtspr variants it is possible that this change
will break some mpc8xx assembly code.  ie. you might need to modify
makefiles to pass -m860 to gas.

include/opcode/
	* ppc.h (PPC_OPCODE_750, PPC_OPCODE_7450, PPC_OPCODE_860): Define.
opcodes/
	* ppc-opc.c (PPC750, PPC7450, PPC860): Define using PPC_OPCODE_*.
	* ppc-dis.c (ppc_opts): Add 821, 850 and 860 entries.  Add
	PPC_OPCODE_7450 to 7450 entry.  Add PPC_OPCODE_750 to 750cl entry.
gas/
	* config/tc-ppc.c (md_show_usage): Add -m821, -m850, -m860.
	* doc/c-ppc.texi (PowerPC-Opts): Likewise.
gas/testsuite/
	* gas/ppc/titan.d: Correct mfmcsrr0 disassembly.
