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.
