ELF targets (and maybe COFF) use relocations when referring to strings in the .debug_str section. Handle that in the accelerator table dumper. This commit restores the test/DebugInfo/cross-cu-inlining.ll test to its expected platform independant form, validating that the fix works (this test failed on linux boxes). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222029 91177308-0d34-0410-b5e6-96231b3b80d8
