I don't think it's possible for the debug info for nullptr_t to
be of any form other than a DW_TAG_unspecified_type with a name of
"nullptr_t" -- at least there doesn't seem to be a way to get Clang
to spit out something else.  (For that matter, it isn't clear to me
why DIBuilder::createNullPtrType lets you specify the name.)  Eric?
