        <pre>* SUMMARY
Remove LegacyProfiler.

The Sampling Profiler does not require extra byte codes / recompilation, and is significantly faster. Once all ports enable SAMPLING_PROFILER we should remove the LegacyProfiler.

Bugs to update when old profiler and tests are removed:
&lt;<a href="https://webkit.org/b/148819">https://webkit.org/b/148819</a>&gt; Enabling the profiler shouldn't prevent us from performing tail call elimination
