Here are the sunspider results:
** TOTAL **:           *1.007x as slow*  852.3ms +/- 0.1%   858.3ms +/- 0.1%   
 significant

Adding UNLIKELY macros in the checks inside the operator new statements, shaved
off about 2ms:
** TOTAL **:           *1.005x as slow*  852.3ms +/- 0.1%   856.1ms +/- 0.1%   
 significant

Is this acceptable?

I'm not sure I understand the second part of your comment. Do you mean to say
there should be a way to enable performance profiling without enabling memory
profiling?
If that is the case, I will include this in the next version of the patch.
