FpuPackerPlugin

class FpuPackerPlugin extends FiberPlugin with RegFileWriterService

Implement the floating point rounding, recode the result into (ieee 754) and then writeback it back into the register file using the WriteBackPlugin. Subnormal recoding will stall the pipeline 2 extra cycles to save FMax.
