Remove remaining uses of REAL_VALUES_IDENTICAL

This patch continues the removal of real-related macros.
We already had both the old-style REAL_VALUES_IDENTICAL and the
new-style real_identical, so this patch replaces all remaining
uses of the former with the latter.

Bootstrapped & regression-tested on x86_64-linux-gnu.  Also tested by
building one target per CPU directory and checking that there were
no new warnings and no changes in testsuite output at -O2.

gcc/
	* real.h (REAL_VALUES_IDENTICAL): Delete.
	* config/m68k/m68k.c (standard_68881_constant_p): Use real_identical
	instead of REAL_VALUES_IDENTICAL.
	* fold-const.c (operand_equal_p): Likewise.
	* ipa-icf.c (sem_variable::equals): Likewise.
	* tree-complex.c (some_nonzerop): Likewise.
	(expand_complex_multiplication): Likewise.
	* tree.c (simple_cst_equal): Likewise.
	* varasm.c (compare_constant): Likewise.
