Chrome part of exception handling support. The debugger is attached when new chrome process

connects to the browser process but before start ipc message is sent. This is needed due
to windows bug when process crashes if debugger is attached before process is started.

TEST= ui_tests --gtest_filter=NaClTestEnableHardwareExceptions.Exception
