vapier@chromium.org 8586f6e288 increase exception handler stack size for dumping thread

When running unittests under ASAN, we see that these code paths can
slightly smash the stack.  Double it to avoid that.

data

The symbol files necessary for the processor to walk stacks on Linux that have __kernel_vsyscall at innermost frame. Special symbol files ar eneeded because EBP does not point to the frame when a thread is inside a system call.
