	* config/i386/i386.c (ix86_print_operand): Remove dead code that
	tried to avoid (%rip) for call operands.

	* config/i386/i386.c (ix86_print_operand_address_as): Add no_rip
	argument.  Do not use RIP relative addressing when no_rip is set.
	(ix86_print_operand): Update call to ix86_print_operand_address_as.
	(ix86_print_operand_address): Ditto.
	* config/i386/i386.md (*movabs<mode>_1): Use %P modifier for
	absolute movabs operand 0.  Add square braces for -masm=intel.
	(*movabs<mode>_2): Ditto for operand 1.
