#   runs.sh suite NAME ROUNDS [WORK ...]   the suite on NAME three ways: the
#                                          compiled code (jit), the executor
#                                          with its batches (batches,
#                                          PURE_JIT=0), the executor alone
#                                          (rounds, PURE_BATCH=0 too)
#   runs.sh counts NAME [WORK ...]         user-mode instructions and cycles
