Bring from lto-branch:

	2008-09-03  Doug Kwan  <dougkwan@google.com>

	* cgraphbuild.c (initialize_inline_failed): Use cgraph_inline_failed_t
	enums instead of reason strings.
	* cgraph.c (cgraph_create_edge): Same.
	(cgraph_inline_failed_string): New function.
	* cgraph.h (cgraph_inline_failed_t): New enum type.
	(cgraph_inline_failed_string): New prototype.
	(struct cgraph_edge): Change type of INLINED_FAILED from constant
	char pointer to cgraph_inline_failed_t.
	(cgraph_inline_p): Adjust prototype to use cgraph_inline_failed_t.
	(cgraph_default_inline_p): Ditto.
	* gcc/cgraphunit.c (cgraph_inline_p): Change type of parameter REASON
	to cgraph_inline_failed_t pointer.
	* cif-code.def: New file.
	* ipa-inline.c (cgraph_mark_inline_edge): Use an enum instead of a
	reason string.
	(cgraph_check_inline_limits): Change type of REASON to pointer to
	cgraph_inline_failed_t.  Replace reason strings with enums.
	(cgraph_default_inline_p): Ditto.
	(cgraph_recursive_inlining_p): Ditto.
	(update_caller_keys): Change type of FAILED_REASON to
	cgraph_inline_failed_t.
	(cgraph_set_inline_failed): Change type of REASON to pointer to
	cgraph_inline_failed_t.  Call cgraph_inline_failed_string to
	convert enums to strings for text output.
	(cgraph_decide_inlining_of_small_function): Change FAILED_REASON
	to be of type cgraph_inline_failed_t.  Replace reason strings with
	enums.  Call cgraph_inline_failed_string to covert enums
	to strings for text output.
	(cgraph_decide_inlining): Replace reason strings with enums.
	(cgraph_decide_inlining_incrementally): Change type of FAILED_REASON
	to cgraph_inline_failed_t type.  Call cgraph_inline_failed_string
	for text output.
	* tree-inline.c (expand_call_inline): Change type of REASON
	to cgraph_inline_failed_t.  Replace reason strings with enums.
	Call cgraph_inline_failed_string for text output.
	* Makefile.in (CGRAPH_H): Add cif-code.def to dependencies.
	(cgraph.o): Ditto.
