Denis Drakhnia 1d0e52b6a0 e2k: Bug fixes. 
Fix time fields in stat64.

Restore and save a breakpoint frame in a signal
handler. This will fix a segfault if a signal will
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.
