Add support to softfloat for flushing input denormal float32 and

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.

No conflicts spotted. If it's semantically correct, fine with me.
