Get rid of the eir struct mips_fpu_emulator_private member. It's
never initialized been initialized anywhere, just saved to and
restored from signal frames so nonsense anyway. As neat side effect
of being shared between all processors it was also abusable as a
nice covert channel between processes.

__compute_return_epc() uses CFC1 instruction which might result in a
coprocessor unusable exception since the process can lose its fpu
context by preemption.
