test/DebugInfo: Convert some tests to MIR
These tests are meant to test dwarf emission (or prolog/epilogue generation) so we can convert them to .mir and only run the relevant part of the pipeline. This way they become independent of changes in earlier passes such as my planned changes to RegAllocFast. llvm-svn: 345919
