That was complete failure - builders are broken,
but original cl worked fine on my system.
I will need access to builders
to test this change properly.

We mark DBG_PRINTEXCEPTION_C messages in VEH handler
as handled, thus preventing debugger from seeing them.
I don't see reason for doing that. The comment warns
of crashes, but I added test and don't see any crashes.
This is also simplify VEH handler before making
changes to fix issue 8006.
Update #8006

I have made mistake while converting it to Go (CL 132820043).
Added test as penance for my sin.
