	* ppc.h (ppc_parse_cpu): Update prototype.
opcodes/
	* ppc-dis.c (ppc_parse_cpu): Add "sticky" param.  Track bits
	set from ppc_opts.sticky in it.  Delete "retain_mask".
	(powerpc_init_dialect): Choose default dialect from info->mach
	before parsing -M options.  Handle more bfd_mach_ppc variants.
	Update common default to power7.
gas/
	* config/tc-ppc.c (sticky): New var.
	(md_parse_option, ppc_machine): Update ppc_parse_cpu calls.
gas/testsuite/
	* gas/ppc/astest2.d: Pass -Mppc to objdump.
ld/testsuite/
	* ld-powerpc/plt1.d: Update for default "at" branch hints.
	* ld-powerpc/tlsexe.d: Likewise.
	* ld-powerpc/tlsexetoc.d: Likewise.
