Log:
        PR c++/92974 - bogus location for enum and non-enum in ?: warning.

build_min_non_dep wasn't setting any location so when we were emitting the
warning in the following test while instantiating a template, its location
was UNKNOWN_LOCATION.  Rather than adding a location_t parameter, let's use
the location from the original expression.

        * tree.c (build_min_non_dep): Use the location of NON_DEP when
        building the expression.

        * g++.dg/diagnostic/enum1.C: New test.
        * g++.dg/gomp/loop-2.C: Adjust dg-error.
        * g++.dg/gomp/for-21.C: Likewise.
