Add a "nop filler" pass to SPU.
...
Filling no-ops is done just before emitting of assembly,
when the instruction stream is final. No-ops are inserted
to align the instructions so the dual-issue of the pipeline
is utilized. This speeds up generated code with a minimum of
1% on a select set of algorithms.
This pass may be redundant if the instruction scheduler and
all subsequent passes that modify the instruction stream
(prolog+epilog inserter, register scavenger, are there others?)
are made aware of the instruction alignments.

Fix PR 8916 (qv for analysis), at least the immediate problem.

There's an inherent tension in DAGCombine between assuming
that things will be put in canonical form, and the Depth
mechanism that disables transformations when recursion gets
too deep. It would not surprise me if there's a lot of little
bugs like this one waiting to be discovered. The mechanism
seems fragile and I'd suggest looking at it from a design viewpoint.
