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.

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.

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.

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.
