* Add scripts for benchmarking and profiling pwndbg commands
* Fix performance issue in emulator.py
Register to unicorn enum lookup was really ineffective. Replaced with
parsing (consts) on initialization time, and only dict lookup on hot path.
* Fix performance issue in syntax_highlight.
Current code initialized pygments on each syntax_highlight(), which
apparently took some time.
* Minor performance improvements in syntax_highlight
* Memoize IDA availability.
Not sure it this is a valid solution, I have never used pwndbg with IDA.
However, we should not try to connect to ida on each context(), as this
takes 25% of current exec time.
* Explicitly source gdbinit in benchmark scripts.
