[ELF] - Add testcase testing .gdb_index generation when base address of CU is used. Recently (before r312477) lib/DebugInfo incorrectly handled the case when debug ranges uses base address of CU. Section index was not calulcated properly and LLD crashed on provided testcase. Differential revision: https://reviews.llvm.org/D37297 llvm-svn: 312478
