llvm-6502/test/DebugInfo/X86/cu-ranges.ll
Eric Christopher 14ec6808c4 If we're only emitting line tables for a particular CU then don't add
any ranges to the list of ranges for the CU as we don't want to emit
them anyway. This ensures that we will still emit ranges if we have
a compile unit compiled with only line tables and one compiled with
full debug info requested (we'll emit for the one with full debug info).

Update testcase metadata accordingly to continue emitting ranges.
