Makefile.in (OBJS): Added tree-inline.o.

* Makefile.in (OBJS): Added tree-inline.o.
(c-common.o): Depend on tree-inline.h.
(tree-inline.o): New target.
* c-common.c: Include tree-inline.h.
(c_mark_lang_decl): Don't mark saved_tree.
(c_common_lang_init): Set lang_anon_aggr_type_p.
* c-common.h (walk_tree_fn, DECL_SAVED_TREE): Moved to tree.h.
(struct c_lang_decl): Moved saved_tree to tree_decl.
* ggc-common.c: Mark saved_tree and inlined_fns of FUNCTION_DECLs.
* integrate.h (function_attribute_inlinable_p): Declare it.
* integrate.c (function_attribute_inlinable_p): Export it.
* tree-inline.c: New file.  Define variables declared in...
* tree-inline.h: New file.  Declare functions to be moved to
tree-inline.c.  Define macros and declare types and hooks for
language-specific tree inlining.
(flag_inline_trees): Moved definition from cp/decl2.c.
* tree.h (walk_tree_fn, DECL_SAVED_TREE): Moved from c-common.h.
(TREE_READONLY_DECL_P, DECL_INLINED_FNS): Moved from cp/cp-tree.h.
(struct tree_decl): Moved saved_tree from c_lang_decl and
inlined_fns from C++'s lang_decl.
