Show variables that were in the debug info but optimized out. Also display a good error message when one of these variables get used in an expression.

ProcessMonitor improvements for Linux.
-Remove tracing of fork/vfork until we add support for tracing inferiors' children on Linux.
-Add trace exec option for ptrace so that we don't receive legacy SIGTRAP signals on execve calls.
-Add handling of SIGCHLD sent by kernel (for now, deliver the signal to the inferior).

The Linux process plugin wasn't returning the correct linux signals. This fixes that.
Thus, this patch also negates a previous fix for handling SIGCHLD.

Another fix to make sure that if we aren't able to extract an object file for any reason, we don't crash when trying to parse the debug map info.
