New flag: -fgraphite-dump-cloog.

Browse source 
Introduce a new flag: -fgraphite-dump-cloog. If enabled, graphite
dumps each SCoP into a CLooG input file for further debugging.
The naming follows the naming scheme of -fgraphite-write:
 <basename>.<scopnumber>.cloog

The file is dumped into the current working directory.

	* common.opt (fgraphite-dump-cloog): New flag.
	* doc/invoke.texi (-fgraphite-dump-cloog): Documented.
	* graphite-clast-to-gimple.c (init_cloog_input_file): New.
	(build_cloog_prog): Dump CLooG input file when
	flag_graphite_dump_cloog is set.
	* graphite-cloog-compat.h (cloog_program_dump_cloog): New.
