5aa8ef1855 Remove invalidation support from BTB 
Validating the target PC in the pipeline is cheaper than maintaining
the valid bits and control logic to guarantee the BTB won't ever
mispredict branch targets.

39bee5198d Nasti Puts: decode wmask to determine addr_byte() and op_size() 
This change is TL0 specific; TL2 knows the op_size, and can use
this to do a much simpler one-hot decode of the address.

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.
