for FPU instruction which load data from memory we should access memory first and only then check if it FPU stack overflow

memory access might fault before

Now devices could be compiled separatelly from CPU
...
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...

Speed up compilation process.
...
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed

freeze softfloat-fpu-ver3 branhc and open it for free testing
...
I will continue the development in new softfloat-fpu-ver4 branch
Current version already implements ALL FPU instructions except
FSIN, FCOS, FSINCOS, FPTAN, FPATAN, FYL2XP1, F2XM1, FYL2X
I think it solved all currently reported bugs and feature requests
related to FPU code.
Please write your own test programms and test the implemntation in all ways you can.
Thanks,
Stanislav
