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.

gcc/
	* doc/tm.texi.in (REAL_ARITHMETIC): Delete.
	* doc/tm.texi: Regenerate.
	* real.h (REAL_ARITHMETIC): Delete.
	* config/i386/i386.c (ix86_expand_lround, ix86_expand_round)
	(ix86_expand_round_sse4): Use real_arithmetic instead of
	REAL_ARITHMETIC.
	* config/i386/sse.md (round<mode>2): Likewise.
	* rtl.h (rtx_to_tree_code): Likewise (in comment).
	* explow.c (rtx_to_tree_code): Likewise (in comment).
	* match.pd: Likewise.
	* simplify-rtx.c (simplify_binary_operation_1): Likewise.
	* tree-ssa-math-opts.c (representable_as_half_series_p): Likewise.
	(expand_pow_as_sqrts): Likewise.
	* tree-pretty-print.c (dump_generic_node): Remove code that
	was conditional on REAL_ARITHMETIC being undefined.
