nir/phi-builder: Set the value in the block when creating a phi
After we figure out the value that we are going to return, we have a
loop that walks up the dominance tree and sets the value in each of the
blocks that doesn't have one yet. In the case of the phi, the def is
set to NEEDS_PHI not NULL, so the last one where the phi node actually
goes never gets filled out. This can lead to duplicating the phi node
unnecessarily.

nir/phi_builder: Don't recurse in value_get_block_def
In some programs, we can have very deep dominance trees and the recursion
can cause us to risk stack overflows. Instead, we replace the recursion
with a pair of loops, one at the start and one at the end. This is
functionally equivalent to what we had before and it's actually a bit
easier to read in the new form without the recursion.

nir: Add a phi node placement helper
Right now, we have phi placement code in two places and there are other
places where it would be nice to be able to do this analysis. Instead of
repeating it all over the place, this commit adds a helper for placing all
of the needed phi nodes for a value.
v2: Add better documentation
