a6f5ca93eb Use the handy MW-derived type for a handy safe-if-inbounds increment 
size limit.

356c7891ee New function for adding to the address unsafely. 
Would used an increment size based on mantissa width, but this is not
available in the type class, so just use 1 byte.
This function is currently used for adding small increments to the PC,
so does not need support for larger offsets.

cbd0b2f7f5 Add a couple of casts for functions that return capabilities. 
This is necessary for passing the register file read functions into modules that want to read the Pipe format rather than the Reg format.
