If those "optimized out"s are an obstacle we should report them to the 
GCC developers. I debugged Emacs with -Og, found an instance of 
"optimized out", turned it into a small test case, and filed a bug 
report with the GCC developers here:

Please feel free to add to it, or to report more bugs in this area.
