  [LLVM][Support] check for error return from dladdr. (#138369)

In case of an error, the DL_info struct may have been left
uninitialized, so it is not safe to use its members.

In one error case, initialize dli_sname to nullptr explicitly, so that
the later check against nullptr is guaranteed to be safe.
