-----------
[JSC] Add a tool to enable profiling of source code that we execute.
https://bugs.webkit.org/show_bug.cgi?id=290147
rdar://146258426
Reviewed by Yijia Huang.
If the JSC::SourceProfiler::g_profilerHook function pointer is set, we'll call
it with the
source code that we will execute. The data is passed to the g_profilerHook in
the form of
a SourceProfiler::Payload struct. The payload is versioned to allow tools to
track format
changes going forward if needed.
If JSC::SourceProfiler::g_profilerHook is not set, this code is a no-op.
