by default. This is a behaviour configurable in the MCAsmInfo. I've decided to turn it on by default in (possibly optimistic) hopes that most assemblers are reasonably sane. If this proves a problem, switching to default seems reasonable. I'm not sure if this is the opportune place to test, but it seemed good to make sure it was tested somewhere. llvm-svn: 154235
