Adds live object profiling capabilities

This version of the patch no longer introduces significant performance
regressions.
Sunspider results are:
http://pastie.org/496608

** TOTAL **:           -                 731.9ms +/- 0.1%   731.2ms +/- 0.1% 

The live object profiling is disabled by default when profiling is enabled. An
explicit action must be performed by the user to enabled it. I have added a
temporary function on the console object that enables or disables live memory
profiling, until this functionality is hooked into the UI. Note that profiling
still needs to be enabled before enabling live object profiling.
