It can be solved almost trivially, IMO, by providing a special -Ox
switch which would turn off every optimization whose results cannot be
expressed reliably using the modern debug info formats.  The gain from
these optimizations is marginal anyway, on the order of several
percents, and many developers will gladly buy that if they gain
debuggability instead.
