  Log Message:
  -----------
  [DebugInfo][AsmPrinter] Don't emit accelerator entries with empty names

The DWARF 5 specification says that:

> All other debugging information entries without a DW_AT_name attribute are
> excluded.

Clang started generating these variables for string literals, see D123534.
