Currently, globals on the device will have an infinite reference count and an unknown name when using `LIBOMPTARGET_INFO` to print the mapping table. We already store the name of the global in the offloading entry so we should be able to use it, although there will be no source location. To do this we need to create a valid `ident_t` string from a name only. Reviewed By: tianshilei1992 Differential Revision: https://reviews.llvm.org/D124381
