Rather than relying on the gmlt-like data emitted into the .o/executable which only contains the simple name of any inlined functions, use the .dwo file if present. Test symbolication with/without a .dwo, and the old test that was testing behavior when no gmlt-like data was present. (I haven't included a test of non-gmlt-like data + no .dwo (that would be akin to symbolication with no debug info) but we could add one for completeness) The test was simplified a bit to be a little clearer (unoptimized, force inline, using a function call as the inlined entity) and regenerated with ToT clang. For the no-gmlt-like-data case, I modified Clang back to its old behavior temporarily & the .dwo file is identical so it is shared between the two executables. llvm-svn: 267227
