Add the ability to trace JavaScriptCore garabge collections using dtrace.
Reviewed by Sam Weinig.
- JavaScriptCore.xcodeproj/project.pbxproj: Generate the dtrace probe header
file when building on a new enough version of Mac OS X.
- JavaScriptCorePrefix.h: Add our standard Mac OS X version detection macros.
- kjs/Tracing.d: Declare three dtrace probes.
- kjs/Tracing.h: Include the generated dtrace macros if dtrace is available,
otherwise provide versions that do nothing.
(KJS::Heap::collect): Fire dtrace probes when starting a collection, after the
mark phase has completed, and when the collection is complete.
- wtf/Platform.h: Define HAVE_DTRACE when building on a new enough version of Mac OS X.
