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 401ccafc8c e2k: Fix C++ exceptions for v5+. 
v5+ has different procedure stack layout. Reading
the stack through the acees_hw_stacks syscall
requires to shuffle registers for a backward
compatibility with previous versions.

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.

Denis Drakhnia e404c06a2d e2k: Fix syscall restart. 
We cannot just change the IP address in E2K to restart
the instruction because the same register can be read
and written in the same instruction (and many more
situations), but we can create a fake syscall instruction
and restart it.
