INCL/EXCL operators dont work with SET64 for 32-bit CPUs

INCL/EXCL operators dont work with SET64 for 32-bit CPUs, because in FoxIntermediateBackend.DesignateBuiltinCallDesignator after calling the Convert procedure the argument types become 64-bit, but in the I386.Builtins module for shifts the second parameter is 32-bit.
