Pipelined CPU for Wramp

This implements a pipelined CPU for the Wramp architecture.

Very WIP!

Building

Use CMake to build in the usual way:

mkdir build
cd build
cmake -GNinja ..
ninja

... alternatively use the bootstrap.sh to setup, and then run the run.sh script which will run the linter and simulation:

# First boostrap it...
./bootstrap.sh

# Run as many times as you like
./run.sh
