* added EXC register, which tracks whether or not we've attempted to
read from/write to any system registers.

* Replaced custom CSR type with GRIFT's (but we're not using it
currently)

* added better show instance for GPRs we should migrate this to a
GRIFT pretty printer at some point)

* Fixed a vicious bug in the semantics; unsigned and signed LT were
getting swapped in translation

No-op change to re-trigger Travis.
The previous commits were valid, but github requires Travis builds to
complete successfully before allowing a merge to master.  The Travis
builds did complete, but somehow the communication between Travis and
Github failed, so Github still is waiting for the Travis build.
Pushing this minor change to re-trigger Travis builds so that this
branch can be merged to master.

aa87eb9a45 Delete top-level stack.yaml symlink
To avoid conflicting stack.yaml files when crucible is used a
submodule in another repo with a top level stack.yaml.

Also, update the README to include creating a stack.yaml symlink
before building with stack the first time.
