<h3>Log Message</h3>
<pre>Add WebKit support for an option in Safari's debug menu similar to "Get Bytecode Profile" but for the Sampling Profiler's data
https://bugs.webkit.org/show_bug.cgi?id=161785
Reviewed by Tim Horton.
Source/WebCore:
* ForwardingHeaders/runtime/SamplingProfiler.h: Added.
Source/WebKit2:
This patch follows in the steps of how we dump output for the
internal JSC bytecode profiler tool, but now also for the internal
JSC sampling profiler tool. This can be used when doing performance
analysis work analyzing the JS execution of a page.
