This commit leaves "b" aliased to the old _regexp-break for now. The two variants are identical except that `_regexp-break` allows you to say: `(lldb) b <unrecognized_input> ` which gets translated to: `break set <unrecognized_input> ` So switching people to `_regexp-break-add` would be a surprising behavior change. It would be wrong for `_regexp_break-add` have one branch that call `break set`, so to avoid surprise, I'll add the command and let people who are playing with `break add` instead of `break set` can set the alias to the new one by hand for now.
