Remove remaining uses of REAL_ARITHMETIC

This patch replaces all remaining uses of the old target macro
REAL_ARITHMETIC with calls to the (now generic) real_arithmetic
function.

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/ada/
	* gcc-interface/trans.c (convert_with_check): Use real_arithmetic
	instead of REAL_ARITHMETIC.

	* doc/tm.texi.in (REAL_ARITHMETIC): Delete.
	* doc/tm.texi: Regenerate.

	* config/i386/i386.c (ix86_expand_lround, ix86_expand_round)
	(ix86_expand_round_sse4): Use real_arithmetic instead of
	REAL_ARITHMETIC.
