When exec is constant, we can remember the constant as the old exec,
and just copy the condition and use it as the new exec. There is no
need to save the constant.
Due to using p_parallelcopy which is lowered to s_mov_b64 (or 32),
many exec restores now become copies, hence the increase in the copy
stats.

Previously, we would store even the constant -1 exec mask from the
beginning of every merged shader. With this change it is no longer
necessary because we can restore to constant exec mask directly.
Hence, this frees up a register pair (single register for Wave32)
in every merged shader.

We don't want to have to deal with vector phis in freedreno, because
vectors are always split/unsplit around vectorized instructions anyways,
and the stated reason for not scalarising them (it hurting coalescing)
won't apply to us because we won't be using nir_from_ssa. Add this
option so that we don't have to do the equivalent thing while
translating from NIR.

The initial value needs to be taken from the instruction that is being
moved over, not the one to be moved.
Additionally the parameter of this function was removed because it was
misleading. Setting it to any value other than source_idx would cause
register_demand to be initialized incorrectly. (Instead, the maximum
demand among the covered instructions would need to be determined.)

multi-planar formats on GFX9+. Since then, the radv check has been out
