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.

0baa1c9a45 coreplex: CacheBlockOffsetBits was wrong! 
This bug is ancient. I don't understand how it never mattered before.
Anyway, in processors with a custom CacheBlockBytes, this value is wrong!
The symptom is that TL1 components end up missing high address bits.
This causes, for example, a system to jump to 0 instead of RAM.

I don't understand how this very serious bug did not cause problems before.

ed4224dde4 tilelink2 AtomicAutomata: fix AccessAck on same cycle as PutFull 
If we send out the PutFull portion of an AMO, the slave is allowed
to respond with AccessAck on the same cycle. In this case, we are
still in the AMO state, but must still match the D response.

aabd17d935 rocketchip: must create bundles within Module scope 
1. Bundles be created after base class Module constructor runs
2. Bundles must be created before Module(...) runs

Solution: pass a bundle constructor to the cake base class

Require the constructor to take a parameter so people don't use it by
accident; they should get a type error.

Consistently name all the cake arguments with an _io, _coreplex, _outer,
so that they don't shadow the base class variables you should be using.
