Wesley W. TerpstraandHenry Cook 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.

This makes it posisble to use Parameters to control Monitors.
However, we need to make all LazyModules carry Parameters.

Wesley W. TerpstraandAndrew Waterman 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.

Wesley W. Terpstra 6aeadc4551 regression: disable ComparatorL2Config for now 
This tests atomics against the L2.  However, we don't have an L2 yet so this
is hitting the broadcast hub, which does not support these operations.
