…prefetching

- tracer: Add WIP version of the iDMA tracer (#9), add some fixes (#14)
- frontends/desc64: Transition Regbus master to AXI master
- jobs.json: Add descriptor-based testbench to the job file
- frontends/desc64: Update synth module for descriptor frontend
- test/frontends: Add testbench for benchmarking (***caution: not to be used as VIP***)
- frontends/desc64: Remove unused shared counter
- Makefile: Quote paths to handle spaces in paths
- frontends/desc64: Add prefetching design
Some changes were necessary for the prefetching to work, e.g.
ignoring mis-speculations that have X in them.
There is no use instantiating these outside the speculation branch,
so don't.
