70b677ecda Vec considered harmful; use isOneOf instead (#64) 
Vec is heavyweight and really should only be used for I/O and
dynamic indexing.  A recurring pattern in uncore is

    Vec(const1, const2, const3) contains x

which is nice but has a deleterious effect on simulation copilation
and execution time.  This patch proposes an alternative:

    x isOneOf (const1, const2, const3)
    x isOneOf seqOfThings

I think it's also more idiomatic.

This is just a prototype; I'm not wed to the name or implementation.

39bee5198d Nasti Puts: decode wmask to determine addr_byte() and op_size() 
This change is TL0 specific; TL2 knows the op_size, and can use
this to do a much simpler one-hot decode of the address.

354b81c8fe Remove legacy HTIF things 
The SCR file is gone, too, because it is tightly coupled.  The
general concept could be revived as a module that somehow connects
to (or is contained by) the debug module.
