Checkpoint after fast-forward specific amount of instructions in MARSS

/*
 * checkpoint_after.c
 *
 * Create a checkpoint after Specifiec amount of user-level-instructions.
 *
 * Usage: ./checkpoint_after N CHK_NAME
 *        N            Number of user-level-instructions to fast-forward
 *        CHK_NAME     Name of checkpoint
 *
 * To change instruction counting from user level to all, in line 36 change
 * -fast-fwd-user-insns to -fast-fwd-insns
