c10691b616 Don't take interrupts on instructions in branch shadow 
In situations like

       j 1f
       nop
    1: nop

the interrupt could be taken on the first nop.

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.

354b81c8fe Remove legacy HTIF things 
The SCR file is gone, too, because it is tightly coupled.  The
general concept could be revived as a module that somehow connects
to (or is contained by) 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.
