If enabling fp traps for first time, clear sticky exceptions.

Otherwise, the indeterminate state of the sticky exceptions --
possibly from another thread -- may cause the machine to trap merely
by enabling traps.

Also, don't bother marking the floating-point environment in use when
disabling traps.
