46b1519cb0 mkXBar: Simplify as fallback case handles priority case correctly 
The first element in the vector will be srcRR[dst], so the special case
is unnecessary.

afd636a0f5 mkXBar: Fix bias towards earlier sources 
In the case where the prioritised round-robin source does not have a
request, this was always picking the earliest source that had one, which
means if some sources are making more requests than others (e.g. there
is lots of D$ churn but the I$ has a high hit rate) then, whilst the
cycles where srcRR[dst] prioritises a source that is making requests are
fair, the cycles where it prioritises a source that is not making
requests is not fair, since then the earlier sources will be
prioritised. Instead, make the fallback priority similarly dynamic so we
cycle through the order we look at the sources in.

fcea5365f6 Initial implementation CLoadTags 
This currently just loads in the data on cache miss, so won't help to reduce DRAM overhead, but will be forwards compatible and save on instructions in the revoker loop.

8da520175f 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.)

fa9931b64c 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.

b830f4bf41 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.
