Force gdb to not print entry values.
All of a sudden gdb decided to start printing them, which messed up the
breakpoint test. It would only print them in the test, not if I manually
ran the same commands. I'm sure it's my fault somehow, but this should
keep things consistent in the future.

Make sure to fence.i after setting/clearing a swbp
This doesn't change anything since Debug ROM already executes a fence.i,
but it will be more correct if that is no longer necessary.

Clean up how Debug ROM is included.
I'm not thrilled about including a static copy in so many cc files, and
making the compiler throw it out. But without really grokking the
Makefile this is the best it's going to be.

Can jump to and execute Debug ROM.
Connect with gdb, and the core will jump to Debug ROM and start
executing it. Then it crashes when it jumps to 0x400 because Debug RAM
isn't implemented (and doesn't live there anyway, for now).
