Since r199356, we've printed a warning when dropping debug info. r225562 started crashing on that, since it registered a diagnostic handler that only expected errors. This fixes the handler to expect other severities. As a side effect, it now prints "error: " at the start of error messages, similar to `llvm-as`. There was a testcase for r199356, but it only really checked the assembler. Move `test/Bitcode/drop-debug-info.ll` to `test/Assembler`, and introduce `test/Bitcode/drop-debug-info.3.5.ll` (and companion `.bc`) to test the bitcode reader. Note: tools/gold/gold-plugin.cpp has an equivalent bug, but I'm not sure what the best fix is there. I'll file a PR. llvm-svn: 230416
