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.
