1. modify shader_core_ctx::execute_pipe() to model instruction throughput correctly (off-by-one error)

2. adding code to dump_pipeline to display reason for memory stage stalling
3. removing dead code resulting from prior changes

correlation vs. GT200 is 0.95 (need to add back modeling of memory writebacks, shared memory latency)
