target-ppc: fix sNaN propagation
The current FPU code returns 0.0 if one of the operand is a signaling NaN and the VXSNAN exception is disabled. fload_invalid_op_excp() doesn't return a qNaN in case of a VXSNAN exception as the operand should be propagated instead of a new qNaN to be generated. Fix that by calling fload_invalid_op_excp() only for the exception generation (if enabled), and use the softfloat code to correctly compute the result.
