Use compressed code if the target supports it.
The main change was to read misa before running any other test. If misa
indicates C is supported, then use compressed code. This required
changing some tests, mostly to ensure correct alignment. The single
step test also needs to know the correct addresses to step through in
compressed code.
Only print at most 1000 lines from each log file.
