10deb1d62b nak: Legalize vector sources 
It is possible for a single scalar to show up in any number of vector
components, including twice in the same vector.  Add a bit to the
legalization pass to deal with this possibility.

9ef47c8921 nak: Rework vector handling 
Previously, we handled vectors by giving each SSAValue a number of
components which we assume matches in all uses.  To deal with swizzles
and component selection, we had OpVec and OpSplit instructions to
convert vectors to/from scalars as-needed.  This is fine as an SSA
representation but it leads to a lot of redundant values when it comes
time for assigning registers.  There are strategies for dealing with
this such as ensuring that splits always kill the whole vector and then
re-combining into a new vector for later uses.  It's possible by doing
this to ensure that each component only ever exists exactly once at the
cost of a LOT of vec/split instructions.

Another possible solution is to naievely emit vec/split but teach
liveness analysis and RA bout the duplicated values.  Instead of RA
working on individual SSA values, it can work on equivalence classes of
components.

This takes a different (and currently novel to Mesa) approach of making
each SSAValue a single component but having an SSARef type which can
reference up to 4 SSAValues as a vector.  Register allocation then works
on individual components and only ensures that the components of a
vector are contiguous when it's used as a vector.  This isn't very
different from how it worked before.  If anything, it's a bit more
straightforward now because the component/vector split uses the same
types as the rest of the IR and the SSAComp is gone.
