Fix the Nasti to Smi Converter for single-word Nasti busses
...
There's a register that tracks what word within a Nasti transaction a
Smi response cooresponds to, since Smi itself doesn't have any
multi-word stuff. This breaks the single-word Nasti to Smi converter
due to what's essentially a 0-width wire bug: it ends up doing something
like
word_offset_into_nasti := nasti_address(3, 3)
when "word_offset_into_nasti" should really be a 0-bit register, but due
to some log2Up block size calculation logic it's actually a 1-bit
register. Thus, this expression ends up grabbing a bit of the address,
which causes odd addresses to get buffered incorrectly.
My fix is to just special-case the "Nasti bus width is the same as Smi
bus width" case.

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.
