Subject: [PATCH] [Pass] Add some missing passes

When dumping IR pipeline in unit test, these passes show their class names,
so add them to pass builder to ensure all names are populated.
Also, when invoke `opt -print-pipeline-passes` without `-S`, it will print:
Could not parse dumped pass pipeline: unknown module pass 'BitcodeWriterPass'
