emit-rtl.c, [...]: Remove all #ifndef REAL_ARITHMETIC blocks...

	* emit-rtl.c, final.c, fold-const.c, gengenrtl.c, optabs.c,
	print-tree.c, real.c, real.h, recog.c, rtl.c, simplify-rtx.c,
	tree.c, config/m68k/m68k.c, f/com.c, f/target.h, java/expr.c,
	java/jcf-parse.c, java/lex.c:
	Remove all #ifndef REAL_ARITHMETIC blocks, make all #ifdef
	REAL_ARITHMETIC blocks unconditional.  Delete some further
	#ifdef blocks predicated on REAL_ARITHMETIC.
	* flags.h, toplev.c: Delete remaining references to
	flag_pretend_float.

	* doc/invoke.texi: Remove documentation of -fpretend-float.
	* doc/tm.texi: Describe the various REAL_* macros as provided by
	real.h, not by the target configuration files.
