d3ccec1044 Massive update containing several months of changes from the now-defunct private chip repo. 
* Adds support for a L2 cache with directory bits for tracking L1 coherence (DefaultL2Config), and new metadata-based coherence API.
* Additional tests.
* New virtual memory implementation, priviliged architecture (1.7), custom CSRs, FDivSqrt unit
* Updated TileLink protocol, NASTI protocol SHIMs.
* Lays groundwork for multiple top-level memory channels, superscalar fetch.
* Bump all submodules.
