Export the single step function from the AArch64 simulator.
* interp.c (sim_create_inferior): Allow for being called with a NULL abfd parameter. If a bfd is provided, initialise the sim with that start address. * simulator.c (HALT_NYI): Just print out the numeric value of the instruction when not tracing. (aarch64_step): Change from static to global. * simulator.h: Add a prototype for aarch64_step().
