Move make_location from tree.h/c to input.h/c
For some reason I added make_location and some related functions to tree.h/c, rather than to input.h/c. Move them there, so we can use them without requiring tree, and add some selftest coverage. gcc/ChangeLog: * input.c (get_pure_location): Move here from tree.c. (make_location): Likewise. Add header comment. (selftest::test_accessing_ordinary_linemaps): Verify pure_location_p, make_location, get_location_from_adhoc_loc and get_range_from_loc. * input.h (get_pure_location): Move declaration here from tree.h. (get_finish): Likewise for inline function. (make_location): Likewise for declaration. * tree.c (get_pure_location): Move to input.c. (make_location): Likewise. * tree.h (get_pure_location): Move declaration to tree.h. (get_finish): Likewise for inline function. (make_location): Likewise for declaration. libcpp/ChangeLog: * include/line-map.h (source_location): Fix line numbers in comment. From-SVN: r238792
