Annoyingly, this requires that we implement integer division on the
command streamer. Fortunately, we're only ever dividing by constants so
we can use the mulh+add+shift trick and it's not as bad as it sounds.

In order to allow nir_gather_xfb_info to be used on OpenGL,
specifically ARB_gl_spirv.
So, from OpenGL 4.6 spec, section 11.1.2.1, "Output Variables":
"outputs specifying both an *XfbBuffer* and an *Offset* are
captured, while outputs not specifying both of these are not
captured. Values are captured each time the shader writes to such
a decorated object."
This implies that are captured if both are present, and not if one of
those are lacking. Technically, it doesn't explicitly point that
having just one or the other is a mistake. In some cases, glslang is
adding some extra XfbBuffer without XfbOffset around, and mentioning
that technically that is not a bug (see issue#1526)
And for the case of Vulkan, as the same glslang issue mentions, it is
not clear if that should be a mistake or not. But even if it is a
mistake, it is not really needed to be checked on the driver, and we
can let the validation layers to check that.
v2: simplify explicit_xfb_buffer and explicit_offset checks (Jason).

Before, we were double-counting the component slots when we had a dvec3
or dvec4. Instead, just add them in once and manually offset the
recorded output offset.

If we have a transform feedback output like:
float[2] x2_out (VARYING_SLOT_VAR1.x, 0, 0)
which is lowered by nir_lower_io_arrays_to_elements to,
float x2_out (VARYING_SLOT_VAR1.x, 0, 0)
float x2_out@5 (VARYING_SLOT_VAR2.x, 0, 0)
We have to update the destination offset to avoid overwriting
the same value.

Instead of setting interface_type to whatever the per-vertex type is, we
only set it on blocks. This allows later passes to tell the difference
between variables that are in blocks and those that aren't.

Instead of splitting every per-vertex struct, just split the ones that
are actually blocks. The reason for the split is so that we have
separate variables for separate locations, qualifiers, and builtin
decorations. The vulkan spec only allows these on members of blocks.

If we want to use a scalar instruction with two sources, both sources have
to be in the same register. This covers a common case by inserting a scalar
MOV into a previous instruction with only a vector alu instruction.
A better method would be to have the sources end up in the same register in
the first place, but when one source is a constant this is the only way.
