This fixes the shadow validity setup of SP,IA and FPC. The current
code misses a char * cast and thus uses a wrong pointer for memset.
This resulted in corruptions of a thread state for multi threaded
programs. After vex: r2818 the memset did overwrite the tid value
of a thread, making this bug visible.
Lets use the c structures instead of pointer arithmetics.
