* Makefile.in (c-decl.o): Depend on tree-inline.h.

(c-lang.o): Likewise, as well as insn-config.h and integrate.h.
* c-decl.c: Include tree-inline.h.
(c_expand_body): Call optimize_inline_calls. Determine whether
a function is inlinable upfront, and only clear
DECL_SAVED_TREE, DECL_INITIAL and DECL_ARGUMENTS if it isn't.
* c-lang.c: Include tree-inline.h, insn-config.h and integrate.h.
(c_disregard_inline_limits): New function.
(inline_forbidden_p, c_cannot_inline_tree_fn): Likewise.
(c_post_options): Enable tree inlining if inlining is enabled.
Don't inline trees when instrumenting functions.
(c_init): Initialize lang_disregard_inline_limits and
lang_cannot_inline_tree_fn.
* tree-inline.c (initialize_inlined_parameters): Handle calls
with fewer arguments than declared parameters, and fewer
parameters than passed arguments.  Don't assume value is a
DECL.
(declare_return_variable): Convert return value back to the
original type, if it was promoted.
(tree_inlinable_function_p): New function.
(inlinable_function_p): Don't look at DECL_INLINE if we're
inlining all functions.  Make it work with a NULL id.
Re-check DECL_UNINLINABLE after language-specific checks.
(varargs_function_p): Move back to cp/tree.c.
* tree-inline.h (tree_inlinable_function_p): Declare it.
(varargs_function_p): Removed declaration.
* integrate.h (function_attribute_inlinable_p): Declare it.
* integrate.c (function_attribute_inlinable_p): Export it.
(save_for_inline): Don't bother to prepare argvec when not
inlining.
* cse.c (check_for_label_ref): Don't check deleted labels.
