[Patch] Remove all uses of TARGET_FLT_EVAL_METHOD_NON_DEFAULT and poison it

I'm going to hookize TARGET_FLT_EVAL_METHOD, so the current definition
of TARGET_FLT_EVAL_METHOD_NON_DEFAULT will stop working.

The relaxation enabled by TARGET_FLT_METHOD_NON_DEFAULT isn't portable,
and keeping it in place is tricky, so this patch removes it, and poisons
TARGET_FLT_EVAL_METHOD_NON_DEFAULT in system.h to prevent future use.

gcc/

	* defaults.h (TARGET_FLT_EVAL_METHOD_NON_DEFAULT): Remove.
	* system.h (TARGET_FLT_EVAL_METHOD_NON_DEFAULT): Poison.

gcc/c-family/

	* c-opts.c (c_common_post_options): Remove special case for
	TARGET_FLT_EVAL_METHOD_NON_DEFAULT with -fexcess-precision=standard
	in C++.

gcc/java/

	* lang.c (java_post_options): Remove special case for
	TARGET_FLT_EVAL_METHOD_NON_DEFAULT with -fexcess-precision=standard.

gcc/fortran/

	* options.c (gfc_post_options): Remove special case for
	TARGET_FLT_EVAL_METHOD_NON_DEFAULT with -fexcess-precision=standard.

gcc/ada/

	* gcc-interface/misc.c (gnat_post_options): Remove special case for
	TARGET_FLT_EVAL_METHOD_NON_DEFAULT with -fexcess-precision=standard.
