52bb6cd9d9 Configs: use a uniform syntax without Match exceptions (#507) 
* Configs: use a uniform syntax without Match exceptions

The old style of specifying Configs used total functions.  The only way to
indicate that a key was not matched was to throw an exception.  Not only was
this a performance concern, but it also caused confusing error messages
whenever you had a match failure from a lookup within a lookup.  The
exception could get handled by an outer-lookup that then reported the wrong
key as missing.

71c4b000b3 Don't special-case power-of-2 replacement policy for BTB 
PLRU wasn't implemented correctly for the BTB, since it wasn't
increasing the priority on replacement, only on usage.  Regardless,
this should be a second-order effect, so using FIFO always is fine.

09afbbafdb ahb: weaken RegisterRouter assertion 
As written I think it could potentially fail, but what I actually care
about is something weaker that should be true. Assert: nothing lost.
