If there are no parameters, we don't need to create a nir_variable to
hold them...and allocating an array of length 0 is pretty bogus.
Should avoid i965 backend assertions in future patches Jason and I are
working on.

For now, it allows us to refactor the control flow insertion API's so
that there's a single entrypoint (with some wrappers). More importantly,
it will allow us to reduce the combinatorial explosion in the extract
function. There, we need to specify two points to extract, which may be
at the beginning of a block, the end of a block, or in the middle of a
block. And then there are various wrappers based off of that (before a
control flow node, before a control flow list, etc.). Rather than having
9 different functions, we can have one function and push the actual
logic of determining which variant to use down to the split function,
which will be shared with nir_cf_node_insert().
In the future, we may want to make the instruction insertion API's as
well as the builder use this, but that's a future cleanup.

When we insert a single basic block A into another basic block B, we
will split B into C and D, insert A in the middle, and then splice
together C, A, and D. When we splice together C and A, we need to move
the successors of A into C -- except A has no successors, since it
hasn't been inserted yet. So in move_successors(), we need to handle the
case where the block whose successors are to be moved doesn't have any
successors. Fixing link_blocks() here prevents a segfault and makes it
work correctly.

We may delete a control flow node which contains structured jumps to
other parts of the program. We need to remove the jump as a predecessor,
as well as remove any phi node sources which reference it. Right now,
the same problem exists for blocks that don't end in a jump instruction,
but with the new API it shouldn't be an issue, since blocks that don't
end in a jump must either point to another block in the same extracted
CF list or not point to anything at all.

Unlike calling nir_instr_remove(), calling nir_cf_node_remove() (and
later in the series, the nir_cf_list_delete()) implies that you're
removing instructions that may still have uses, except those
instructions are never executed so any uses will be undefined. When
cleaning up a CF node for deletion, we must clean up any uses of the
deleted instructions by making them point to undef instructions instead.

In particular, handle the case where the earlier block ends in a jump
and the later block is empty. In that case, we want to preserve the jump
and remove any traces of the later block. Before, we would only hit this
case when removing a control flow node after a jump, which wasn't a
common occurance, but we'll need it to handle inserting a control flow
list which ends in a jump, which should be more common/useful.

Before, we would only split a block with a jump at the end if we were
inserting something after a block with a jump, which never happened in
practice. But now, we want to use this to extract control flow lists
which may end in a jump, in which case we really need to do the correct
patching up. As a side effect, when removing jumps we now correctly
insert undef phi sources in some corner cases, which can't hurt.

Before, the process of removing a jump and wiring up the remaining block
correctly was atomic, but with the new control flow modification it's
split into two parts: first, we extract the jump, which creates a new
block with re-wired successors as well as a free-floating jump, and then
we delete the control flow containing the jump, which removes the entry
in the predecessors and any phi node sources. Split up
nir_handle_remove_jumps() to accomodate this, and add the missing
support for removing phi node sources.

We want to start reworking and expanding this code, but it'll be a lot
easier to do once we disentangle it from the rest of the stuff in nir.c.
Unfortunately, there are a few unavoidable dependencies in nir.c on
methods we'd rather not expose publicly, since if not used in very
specific situations they can cause Bad Things (tm) to happen. Namely, we
need to do some magical control flow munging when adding/removing jumps.
In the future, we may disallow adding/removing jumps in
nir_instr_insert_*() and nir_instr_remove(), and use separate functions
that are part of the control flow modification code, but for now we
expose them and put them in a separate, private header.

cleanup_cf_node() is part of the control flow modification code, which
we're going to split into its own file, but remove_defs_uses() is an
internal function used by nir_instr_remove(). Break the dependency by
making cleanup_cf_node() use nir_instr_remove() instead, which simply
calls remove_defs_uses() and then removes the instruction from the list.
nir_instr_remove() does do extra things for jumps, though, so we avoid
calling it on jumps which matches the previous behavior (this will be
fixed later in the series).

It's simply the first nir_cf_node in the nir_function_impl::body list,
which is easy enough to access - we don't to store a pointer to it
explicitly. Removing it means we don't need to maintain the pointer
when, say, splitting the start block when modifying control flow.
Thanks to Connor Abbott for suggesting this.

i965/state: Emit pipeline select when changing pipelines
However, we do not reset the cache between batches on context-less
platforms resulting in us not setting the pipeline selection and can
cause GPU hangs if a media pipelined was loaded in the meantime (e.g.
mixing mplayer/gstreamer using libva and gnome-shell). A simple solution
is to just forcibly re-emit the pipeline select along with the invariant
state and reset the cache at that point.

When the edge flag element is enabled then the elements are slightly
reordered so that the edge flag is always the last one. This was
confusing the code to upload the 3DSTATE_VF_INSTANCING state because
that is uploaded with a separate loop which has an instruction for
each element. The indices used in these instructions weren't taking
into account the reordering so the state would be incorrect.
v2: Use nr_elements instead of brw->vb.nr_enabled so that it will cope
when gl_VertexID is used.

The edge flag data on Gen6+ is passed through the fixed function hardware as
an extra attribute. According to the PRM it must be the last valid
VERTEX_ELEMENT structure. However if the vertex ID is also used then another
extra element is added to source the VID. This made it so the vertex ID is in
the wrong register in the vertex shader and the edge attribute is no longer in
the last element.
