* tree.h: Forward-declare struct realvaluetype.
(struct tree_real_cst): Point to the REAL_VALUE_TYPE, do not
contain it.
(TREE_REAL_CST_PTR): New accessor.
(TREE_REAL_CST): Update.
* real.h: Include machmode.h.
(realvaluetype): Make it struct realvaluetype, not a typedef.
(build_real): Prototype here.
* tree.c: Include real.h.
(build_real): Allocate the REAL_VALUE_TYPE as a separate
object in GC memory, set TREE_REAL_CST_PTR to point to it.
(build_real_from_int_cst): Use build_real.
* ggc-common.c (ggc_mark_trees): Mark TREE_REAL_CST_PTR of a
REAL_CST.
* builtins.c, c-common.c, c-lex.c, dwarf2out.c, expr.c,
fold-const.c, print-tree.c, real.c, cp/mangle.c, cp/tree.c,
f/bld.c, f/com.c, f/expr.c, f/target.c, java/decl.c,
java/jcf-parse.c, java/parse.y, java/typeck.c: Include real.h.
* Makefile.in, cp/Make-lang.in, f/Make-lang.in,
java/Make-lang.in: Update dependency lists.
