Wojciech Macek 054a090d49 PPC64: fix TOC behavior on process initialization 
Set stack pointer to correct value after thread's stack pointer restore

Restoring new thread's stack pointer caused stack corruption because
restored stack pointer didn't point to callee (cpu_switch) stack frame but
caller stack frame.

As a result we had mysterious errors in caller function (sched_switch).

Solution: simply set stack pointer to correct value

Also, initialize TOC to a valid pointer once the thread is being
created.
