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):
