That sounds reasonable. At one point there was a proposal to emit
completely accurate unwind information for .debug_frame, and skip some
prologue/epilogue information in .eh_frame; if we do that, obviously
we need both sets of output, but otherwise we don't.
We should make this be consistent though, not depend on
-fno-dwarf2-cfi-asm.
