Dan Elphick cef8ae2483 [compile] Collect RuntimeCallStats for AssembleCode
First this plumbs RuntimeCallStats from the OptimizingCompileDispatcher
down through to PipelineCompilationJob which stashes the
RuntimeCallStats on the PipelineData.

Adds new RCS thread-specific counters: OptimizeAssembleCode and
OptimizeBackgroundAssembleCode which are used in
PipelineImpl::AssembleCode.
