	* config/crx/crx.c: Implemented crx_decompose_address (like in the
	  i386 port) so that crx_legitimate_address_p, crx_address_cost
	  and crx_print_operand_address are using the same code for adress
	  handling. Using symbolic displacements now gets rejected since
	  the CRX register relative adressing mode can't handle unsigned
	  32-bit values as displacements.
	* config/crx/crx.h: Simplified definitions for REG_OK_FOR_BASE_P,
	  removed redundant parenthesis and obsolete macros.
	* config/crx/crx.opt: Added a new switch for debugging of address
	  handling.
	* config/crx/crx-protos.h: Added new declarations for above.
