Alexei Filippov 9a5377780c [cpu profiler] Make profiler work even if enabled before isolate creation. 
TracingCpuProfiler wrapper uses API interrupt to start the profiling
on the Isolate thread. However it could do it before Isolate is
initialized, so the interrupt it requested got lost.

The patch moves TracingCpuProfiler creation after ThreadLocal object
for isolate is initialized.
