libgcc changes for AMD znver1.

2015-10-30  Venkataramanan Kumar  <venkataramanan.kumar@amd.com>

	* config/i386/i386.c (get_builtin_code_for_version): Set priority
	for PROCESSOR_ZNVER1.
	(enum processor_model): Add M_AMDFAM17H_znver1.
	(struct arch_names_table): Likewise.
	* doc/extend.texi: ADD znver1.

2015-10-30  Venkataramanan Kumar  <venkataramanan.kumar@amd.com>

	* config/i386/cpuinfo.c (enum processor_types): Add AMDFAM17H.
	(processor_subtypes): Add znver1.
	(get_amd_cpu): Detect znver1.
