Subject: Add -mlong-double-128 and make it default for 64-bit Bionic

gcc/

	* config/i386/i386.c (flag_opts): Add -mlong-double-128.
	(ix86_option_override_internal): Default long double to 64-bit for
	32-bit Bionic and to 128-bit for 64-bit Bionic.

	* config/i386/i386.h (LONG_DOUBLE_TYPE_SIZE): Use 128 if
	TARGET_LONG_DOUBLE_128 is true.
	(LIBGCC2_LONG_DOUBLE_TYPE_SIZE): Likewise.

	* config/i386/i386.opt (mlong-double-80): Negate -mlong-double-64.
	(mlong-double-64): Negate -mlong-double-128.
	(mlong-double-128): New option.

	* config/i386/i386-c.c (ix86_target_macros): Define
	__LONG_DOUBLE_128__ for TARGET_LONG_DOUBLE_128.

	* doc/invoke.texi: Document -mlong-double-128.
