Replace the `ident_t` handling in Clang with the methods offered by the OMPIRBuilder. This cuts down on the clang code as well as the differences between the two, making further transitions easier. Tests have changed but there should not be a real functional change. The most interesting difference is probably that we stop generating local ident_t allocations for now and just use globals. Given that this happens only with debug info, the location part of the `ident_t` is probably bigger than the test anyway. As the location part is already a global, we can avoid the allocation, memcpy, and store in favor of a constant global that is slightly bigger. This can be revisited if there are complications.
