Remove no-longer-needed fp-bit target macros.

gcc:
	* defaults.h (LARGEST_EXPONENT_IS_NORMAL, ROUND_TOWARDS_ZERO):
	Remove.
	* doc/tm.texi.in (ROUND_TOWARDS_ZERO, LARGEST_EXPONENT_IS_NORMAL):
	Remove.
	* doc/tm.texi: Regenerate.
	* system.h (LARGEST_EXPONENT_IS_NORMAL, ROUND_TOWARDS_ZERO):
	Poison.
	* config/arm/arm.h (LARGEST_EXPONENT_IS_NORMAL): Remove.
	* config/cris/cris.h (__make_dp): Remove.

libgcc:
	* fp-bit.c (pack_d, unpack_d): Remove LARGEST_EXPONENT_IS_NORMAL
	and ROUND_TOWARDS_ZERO conditionals.
