Convert vectors to fixed sized arrays and smallvectors.  Eliminate use of getNode that takes a vector.

_func:
        vsldoi v2, v3, v2, 12
        vsldoi v2, v2, v2, 4
        blr

instead of:

_func:
        vsldoi v2, v3, v2, 12
        vsldoi v2, v2, v2, 4
***     vor f1, v2, v2

in the start of an array and a count of operands where applicable.  In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap.  In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.

I updated a lot of code calling getNode that takes a vector, but ran out of
time.  The rest of the code should be updated, and these methods should be
removed.

We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.

It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

selection is done. That's rather expensive especially in situations where it
isn't really needed.
Move back to a searching the predecessors, but make use of topological order
to trim the search space.
