Log message:

	libmudflap hook breakup:
	* Makefile.am (TESTS_ENVIRONMENT): Add ../../gcc to LD_LIBRARY_PATH
	for libgcc_s.
	(TESTS): Make dependent on libmudflap.
	(HOOKOBJS): Break up mf-hooks.o into many little hook objects,
	compiled from segments of mf-hooks.c.
	* mf-hooks.c: Corresponding changes: wrap each function in
	#ifdef/#endif.
	* Makefile.in: Regenerated.
	
	Heuristics reorganization:
	* mf-heuristics.c (__mf_register_ro_sections, __mf_init_heuristics):
	Remove these functions.  Update callers.
	(__mf_heuristic_check): Incorporate all the various heuristics.
	Encode cacheability/retry judgement into trinary return value.
	Separate start-end logic into a separate fallback heuristic.  Only
	register relevant /proc/self/map segments.
	* mf-impl.h: Corresponding changes.
	* mf-runtime.c (__mf_check): Reorganize heuristics fallback logic.
	(__mf_init): Don't call __mf_init_heuristics.
	
	Tracing cleanup:
	* mf-heuristics.c, mf-runtime.c: Use new MUDFLAP_OPTION
	"-verbose-trace" to emit all tracing messages other than those of
	basic public api.  Eliminate some duplicate/excessive messages.
	* mf-runtime.h: Corresponding changes.
