	PR fortran/52846
	* decl.c (gfc_match_end): Pick out declared submodule name from
	the composite identifier.
	* gfortran.h : Add 'submodule_name' to gfc_use_list structure.
	* module.c (gfc_match_submodule): Define submodule_name and add
	static 'submodule_name'.
	(gfc_match_submodule): Build up submodule filenames, using '@'
	as a delimiter. Store the output filename in 'submodule_name'.
	Similarly, the submodule identifier is built using '.' as an
	identifier.
	(gfc_dump_module): If current state is COMP_SUBMODULE, write
	to file 'submodule_name', using SUBMODULE_EXTENSION.
	(gfc_use_module): Similarly, use the 'submodule_name' field in
	the gfc_use_list structure and SUBMODULE_EXTENSION to read the
	implicitly used submodule files.

This fixes bootstrap of GCC with BOOT_CFLAGS="-g -O2 -fgraphite-identity
-floop-nest-optimize -floop-block -floop-interchange -floop-strip-mine".  It
passes regstrap on amd64-linux.  A previous change
(https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213816), replaced
isl_int with isl_val because isl_int would be deprecated. Since isl_val has
stricter checks, it exposed the bug.  In the test case (isl_set_max_val) would
return infinity which would remain unchecked.  We now check if the value
returned is an integer or not, and bail out if it isn't.  The other problem was
that we were allowing all kinds of data-refs in a scop.  Now we discard a scop
if it has any date-ref other than (ARRAY_REF, MEM_REF, COMPONENT_REF).
