	* target.def (libgcc_floating_mode_supported_p): Take a
	scalar_float_mode.
	* doc/tm.texi: Regenerate.
	* targhooks.h (default_libgcc_floating_mode_supported_p): Take a
	scalar_float_mode.
	* targhooks.c (default_libgcc_floating_mode_supported_p): Likewise.
	* config/aarch64/aarch64.c (aarch64_libgcc_floating_mode_supported_p):
	Likewise.
