Moved some generic stuff from backend.h gen_arm.h and gen_arm.c into gen.h and gen.c. Added a couple fields to cpu_options so that gen_mem_fun can be made guest CPU generic

Use a new fatal_error function instead of calling fprintf and exit for fatal errors. This new function more gracefully handles the case in which BlastEm was not started from a terminal or disconnected from ther terminal (Windows).
