Aleksandar Markovic 64ce541c0b linux-user: Handle EXCP_FPE properly for MIPS 
Handle EXCP_FPE properly for MIPS in cpu loop.

Note that a vast majority of FP instructions are not affected by
the absence of the code in this patch, as they use alternative code
paths for handling floating point exceptions (see, for example,
invocations of update_fcr31()) - they rely on softfloat library for
keeping track on exceptions that needs to be raised. However, there
are few MIPS FP instructions (an example is CTC1) that use function
do_raise_exception() directly, and they need the case that is added
in this patch to propagate the FPE exception as designed.

The code is based on kernel's function force_fcr31_sig() in
arch/mips/kernel.traps.c.
