Don't use -fomit-frame-pointer to build Mac V8. The Chrome crash reporting

system can't currently process stacks produced by gcc -fomit-frame-pointer
properly.  The drawback outweighs the 2% performance improvement.  Once
the crash reporting system is able to handle this optimization, it should be
revisited.
