	* params.def: Introduce parameter max-inline-insns-rtl for
	a separate limit for the RTL inliner.
	* params.h: Likewise.
	* integrate.c (function_cannot_inline_p): Use it.
	* toplev.c (decode_f_option): Set multiple parameters
	controlling inlining with -finline-limit.
	* params.def: Fix orthographic and typographic errors.
	* doc/invoke.texi: Document parameters controlling inlining
	and the way -finline-limit sets multiple of them.

	* tree.h (struct tree_decl): Introduce inlined_function_flag,
	recording whether the function became eligible for inlining
	by a compiler flag rather than the declaration.
	Provide DID_INLINE_FUNC macro to access it.
	* c-decl.c (grokdeclarator): Set DID_INLINE_FUNC.
	* cp/decl.c (grokfndecl): Likewise.
	* toplev.c (rest_of_compilation): Likewise.
	* cp/optimize (maybe_clone_body): Copy DID_INLINE_FUNC.
	* print-tree.c (print_node): Report it.
	* params.def: Introduce new max-inline-insns-auto limit.
	* params.h: Likewise.
	* tree-inline.c (inlinable_function_p): Apply it to functions
	with DID_INLINE_FUNC set.
	* toplev.c (decode_f_option): Initialize it from -finline-limit
	value.
	* doc/invoke.texi: Document new parameter.
