them are generic changes.
- Use the "fast" flag that's already being passed into the asm printers instead
of shoving it into the DwarfWriter.

machine function when calling "runOnMachineFunction" in the asm printers.

a DBG_LABEL or not. We want to fall back to the original way of emitting debug

need to investigate still.
