Feature request: Integrate logic analyzer into the language Signal(trace=True)

[hansfbaier]

It would be fantastic to have a logic analyzer integrated into the language. Most logic analyzers seem to be bolted on and are quite cumbersome to use.

Most basic use case would be something like:

foo = Signal(trace=True)

but also a method for matching signals with regular expressions would be highly useful:

ila.trace_matching_signals("wishbone.*cyc")

Also having the trace trigger command built into the language would be fantastic:

ila.trigger()

Not sure yet about how the data retrieval should work. Maybe a wishbone style memory interface to the ringbuffer or so.

@awygle I came across your twitch stream on this subject. How far have you come? Is the code available somewhere?
