* 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:
<https://webkit.org/b/148819> Enabling the profiler shouldn't prevent us from performing tail call elimination
<https://webkit.org/b/142157> [EFL] Mark two profiler tests to flaky
<https://webkit.org/b/136067> [GTK] Layout Test fast/profiler/dead-time.html and fast/profiler/stop-profiling-after-setTimeout.html are flaky

<https://webkit.org/b/95764> Crashes in fast/profiler layout tests after r127202
<https://webkit.org/b/49801> REGRESSION (r72351): fast/profiler/throw-exception-from-eval.html fails
<https://webkit.org/b/34230> fast/profiler/simple-no-level-change.html crashed on Snow Leopard Release Bot
<https://webkit.org/b/33490> fast/profiler/profile-calls-in-included-file.html crashed on the leopard Commit Bot
