nv50/ir: fix phi/union sources when their def has been merged

In a situation where double-register values are used, the phi nodes can
still end up being u32 values. They all get merged into one RA node
though. When fixing up the merge (which comes after the phi node), the
phi node's def would get fixed, but not its sources which would remain
at the low register value.

This maintains the invariant that a phi node's defs and sources are
allocated the same register.

nvc0/ir: remove merge/split pairs to allow normal propagation to occur

Because the TGSI interface creates merges for each instruction source
and then splits them back out, there are a lot of unnecessary
merge/split pairs which do essentially nothing. The various modifier/etc
propagation doesn't know how to walk though those, so just remove them
when they're unnecessary.
