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.

C++11 has a
  static_assert (COND, MESSAGE)
which gives more readable error messages for STATIC_ASSERT than our
current implementation.

This patch makes us use it if __cplusplus >= 201103L

There's also a provisional static_assert (COND) in C++1z, but presumably
we should wait until that one is fully standardized before using it.

	with C++11 onwards.
