Add Simple Custom Instruction Extension
This enables adding custom instructions that operate on the x-registers (i.e., no additional architectural state). This version on supports combinational units (which fit in the pipeline in the same place as the integer ALU), but it can be extended to support 2-stage pipelines, or multi-cycle operations.
