Add facility to instrument specific opcodes
It's not ideal, because it requires modifying tracer.h. A more general
facility would allow overriding the instruction execution function for
a given opcode dynamically.

allow interactive "reg" command to dump all registers
It you want to scan all the registers at once (or at least a few), having
to dump them one by one is kind of a pain. Change the behavior so that if
the register number is omitted, it'll dump all of them.

add an interactive "pc" command
This lets you show the current pc quickly. Sometimes when displaying
different state you can lose track of what the pc was. Add a simple
command that plumbs in the existing functions to the user interface.

add aliases for common interactive functions
Rather than using one letter commands everywhere, add support for "run"
and "quit" and "help" as aliases to "r" and "q" and "h" respectively.
This makes it a little inconsistent when some commands are one letters
but others are full words.
