49de0f90f0 Reduce VA_Width to allow compilation 
This is almost certainly not the right fix but allows the code to
compile and the trim code is not used anywhere with CAP64

613af39b8f Add functions to compress/decompress the CapMem format where the tag is 
assumed to be set and the address is assumed to be a valid virtual
address.

This is being used for getting realistic area usage for the BTB.

149733072a Don't unseal caps in setBounds 
I'm not sure why this was here, as setBounds on a sealed cap would previously cause a trap anyway.
Maybe left over from when otype bits were shared with the bounds?

bea5e463c6 Blarney wrappers now compile with latest Blarney 
Various minor changes to Blarney wrapper script:
  * Blarney.BV -> Blarney.Core.BV
  * Custom now needs input widths as well as output widths
  * Custom now takes additional argument (netlist generator -> Nothing)
  * makePrim1 now takes 2 params, not 3

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.
