Use an (unguarded) BRAM in the Btb.
...
Also, assume that a target that is not taken should be removed from the
Btb. (The read that checked isn't possible with BRAM timing unless we
latched and had an extra port, but removing the check actually improved
performance a bit in CoreMark, and the pipeline should actually only be
reporting a non-taken branch if we did something wrong.)

Implement a couple Cache counters in the LLCache.
...
These aren't too useful... We don't seem to have normal counters for
loads and stores in the baseline.

Resolve some issues to build on mac.
...
This includes renaming Fifo.bsv to Fifos.bsv to account for a case insensitive file system which confuses this library with FIFO.bsv.
Also this includes an update of the verilator flags that are needed for modern verilator.
Finally, some verilator flag changes for building with LLVM.
