        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.

        (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.
