Reviewed by Tim and Mark.

Implement DTrace hooks for dashcode and instruments.

  • API/JSProfilerPrivate.cpp: Added. Expose SPI so that profiling can be turned on from a client. The DTrace probes were added within the profiler mechanism for performance reasons so the profiler must be started to enable tracing. (JSStartProfiling): (JSEndProfiling):
  • API/JSProfilerPrivate.h: Added. Ditto.
  • JavaScriptCore.exp: Exposing the start/stop methods to clients.
  • JavaScriptCore.xcodeproj/project.pbxproj:
  • kjs/Tracing.d: Define the DTrace probes.
  • kjs/Tracing.h: Ditto.
  • profiler/ProfileGenerator.cpp: Implement the DTrace probes in the profiler. (KJS::ProfileGenerator::willExecute): (KJS::ProfileGenerator::didExecute):
