Subject: nx2: profile engine method calls and semaphore acquires; notes
 140-141

EDEN_NX2_GPU_PROFILE now times engine method calls (the work a split GPU thread's back half
would run) and counts semaphore acquires and those that wait. Title 1: method calls ~343 ms
a second (6.9 million), front-half work (command parsing, macros) ~333 ms, acquires ~2,700 a
second of which ~220 wait. Notes 140 (macro compiler) and 141 (draw setup).
