568bfa6c50 Purge legacy HTIF things 
The SCR file is gone, too, because it was tightly coupled.  The
general concept could be revived as a module that somehow connects
to the debug module.

5644a2703a Avoid need for FENCE.I in debug programs 
This is a hack to work around caching the (uncacheable) debug RAM.  The
RAM is always entered with a JALR, so flush the I$ on any debug-mode JALR.

7f88a00a38 Always verify BTB result; don't bother flushing it 
This improves CPI for things like

    lbu t0, (t0)
    j foo
    addi t0, t0, 1

where the addi would stall, causing j's misprediction check to fail,
flushing the pipeline.

82169e971e Dynamically compute number of L1 client channels 
Until now, the number of L1 client channels was set statically in the
configuration. This static configuration also assumed the same number of
cached and uncached channels per tile. As we plan to move towards
heterogenous multicore systems, this restriction should be removed.

This commit changes the generator so that number of channels per tile
can be independently set (using cde.Parameters.alterPartial).
The OuterMemorySystem will dynamically compute the number of cached and
uncached channels by summing the number of each kind of channel per core.

16bfbda3c9 Refactor the TransactionTracker logic in all the L2 TileLink Managers. 
They now share common sub-transactions within traits, and use a common
set of state transitions and scoreboarding logic. Tracker allocation
logic has also been updated. No changes to external IOs or the TileLink protocol.
A new bufferless Broadcast hub is also included, but does not yet pass fuzzing checks.
