When actually emitting dwarf2, this now produces proper results.
When emitting ia64 unwind info, this removes a hard-coded assumption.

Not that there's much rtl to emit, since the CALL instruction
interpreting the procedure entry mask does almost all the work.
However, it means we're no longer emitting dwarf2 via the
