softfloat: Implement flushing input denormals to zero
Add support to softfloat for flushing input denormal float32 and float64 to zero. softfloat's existing 'flush_to_zero' flag only flushes denormals to zero on output. Some CPUs need input denormals to be flushed before processing as well. Implement this, using a new status flag to enable it and a new exception status bit to indicate when it has happened. Existing CPUs should be unaffected as there is no behaviour change unless the mode is enabled.
