This is just an enforcement of the DWARF requirement that a `DW_TAG_subprogram`
should have a `DW_AT_name`.
This came up when updating how we generating some debug info and one of the
possible change caused several LLDB tests to fail. This was ultimately due to
subprograms being generated without names but the immediate symptom did not
point to that.
