ivopts: Call valid_mem_ref_p with ifn [PR110248]

As PR110248 shows, to get the expected query results for
that internal functions LEN_{LOAD,STORE} is able to adopt
some addressing modes, we need to pass down the related
IFN code as well.  This patch is to make IVOPTs pass down
ifn code for USE_PTR_ADDRESS type uses, it adjusts the
related functions {strict_,}memory_address_addr_space_p,
and valid_mem_ref_p as well.

	PR tree-optimization/110248

gcc/ChangeLog:

	* recog.cc (memory_address_addr_space_p): Add one more argument ch of
	type code_helper and pass it to targetm.addr_space.legitimate_address_p
	instead of ERROR_MARK.
	(offsettable_address_addr_space_p): Update one function pointer with
	one more argument of type code_helper as its assignees
	memory_address_addr_space_p and strict_memory_address_addr_space_p
	have been adjusted, and adjust some call sites with ERROR_MARK.
	* recog.h (tree.h): New include header file for tree_code ERROR_MARK.
	(memory_address_addr_space_p): Adjust with one more unnamed argument
	of type code_helper with default ERROR_MARK.
	(strict_memory_address_addr_space_p): Likewise.
	* reload.cc (strict_memory_address_addr_space_p): Add one unnamed
	argument of type code_helper.
	* tree-ssa-address.cc (valid_mem_ref_p): Add one more argument ch of
	type code_helper and pass it to memory_address_addr_space_p.
	* tree-ssa-address.h (valid_mem_ref_p): Adjust the declaration with
	one more unnamed argument of type code_helper with default value
	ERROR_MARK.
	* tree-ssa-loop-ivopts.cc (get_address_cost): Use ERROR_MARK as code
	by default, change it with ifn code for USE_PTR_ADDRESS type use, and
	pass it to all valid_mem_ref_p calls.
