Fix time fields in stat64.

be raised while a cpu is in a breakpoint.

Denis Drakhnia 17be44b21b e2k: Use one large array for registers. 
Previously was used two separate arrays for low and
high halves of a register. Now we can pass direct
pointer to a register into helpers instead of copying
the halves into a temporary buffer and pass pointer to
that buffer.
