target-i386: update fp status fix
This patch introduces cpu_set_fpuc() function, which changes fpuc field
of the CPU state and calls update_fp_status() function.
These calls update status of softfloat library and prevent bugs caused
by non-coherent rounding settings of the FPU and softfloat.
v2 changes:
* Added missed calls and intoduced setter function (as suggested by TeLeMan)
