If a layer parameter is provided, we want to flip it to position 0 (and
combine it with any indirect params). However if the target is not an
array, there is no layer, so we have to shift all of the arguments down
by one to make room for it.
This fixes situations where there were non-coordinate parameters, such
as bias, lod, depth compare, explicit derivatives. Instead of adding a
new parameter at the front for the indirect reference, we would swap one
of those in its place.

In "manual" derivative mode (always used on nv50 and sometimes on nvc0
but always for cube), the idea is that using the quadop instruction, we
set up the "other" quads to have values such that the derivatives work
out, and then run the texture instruction as if nothing were strange. It
pulls values from the other lanes, and does its magic.
However cube coordinates have to be normalized - one of the 3 coords has
to be 1, to determine which is the major axis, to say which face is
being sampled. We were normalizing the coordinates first, and then
adding the derivatives. This is wrong for two reasons:
- the coordinates got normalized by a scaling factor but the
derivatives didn't
- the result of the addition didn't end up normalized
To resolve this, we flip the logic around to normalize *after* the
per-lane coordinates are set up.
This fixes a bunch of textureGrad cube dEQP tests.
NOTE: nv50 cube arrays with explicit derivatives are still broken, to be
resolved at a later date.

Radeonsi needs to know which shader stage will execute after a shader
in order to make the best decision about which shader variant to compile
first.
This is only set for VS and TES, because we don't need it elsewhere.
VS has 3 variants:
- next shader is FS
- next shader is GS
- next shader is TCS
TES has 2 variants:
- next shader is FS
- next shader is GS
Currently, radeonsi always assumes the next shader is FS, which is suboptimal,
since st/mesa always knows which shader is next if the GLSL program is not
a "separate shader".
By default, ureg always sets "next shader is FS".

Apparently, GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is not allowed when
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is GL_FRAMEBUFFER_DEFAULT, and

No GL specification actually defines what GL_FRAMEBUFFER_DEFAULT means.
It probably means the window system FBO. It also doesn't mention the
behavior of any queries for that type. Various ARB folks seem fairly
confused about it too. For now, just do something vaguely like what
