aix: Default AIX 7.2 to POWER7 server and AIX 7.3 to POWER8 server.

AIX 7.2 minimum ISA is POWER7 and AIX 7.3 minimum ISA is POWER8.
This patch changes the aix72.h configuration to POWER7 with VSX enabled
by default (with the AIX VSX ABI limitations), matching LLVM on AIX,
and changes the aix73.h configuration to POWER8.

gcc/ChangeLog:
	* config/rs6000/aix72.h (TARGET_DEFAULT): Use ISA_2_6_MASKS_SERVER.
	* config/rs6000/aix73.h (TARGET_DEFAULT): Use ISA_2_7_MASKS_SERVER.
	(PROCESSOR_DEFAULT): Use PROCESSOR_POWER8.
