This function retrieves the tess input/output info
from the tess constant buffer that is bound to the shader.
This uses a vfetch to get the values into the shader.

These utilities are to be used to do things like integer adds and
multiplies to be used in calculating the LDS offsets etc.
It handles CAYMAN MULLO differences as well.

When using tessellation on eg/ni chipsets, we must disable
dynamic GPRs to workaround a hw bug where the GPU hangs
when too many things get queued.
This implements something like the r600 code to emit
the transition between static and dynamic GPRs, and to
statically allocate GPRs when tessellation is enabled.

If we have no tess control shader, then we have to use a fallback
one that just writes the tessellation factors.

This creates a constant buffer with the information about
the layout of the LDS memory that is given to the vertex, tess
control and tess evaluation shaders.
This also programs the LDS size and the LS_HS_CONFIG registers,
on evergreen only.
v2: calculate lds hs num waves properly (Marek)
Emit the state only when something has changed (airlied).

This update the setting of the shader stages register
when tess is enabled and add the setting of the VGT_TF_PARAM
register from the tess shader properties.

This initialises the tess min/max using fglrx values,
and also initialises a number of other registers related
to tessellation.
v1.1: caicos doesn't have some registers.

This just adds printing for the hw shader types, and hooks it up.

These are used in tessellation shaders to read/write values
between VS/TCS/TES.
This splits the eg alu assembler out to handle these
instructions.

This function is going to get a lot messier with tessellation
so I'm going to use some macros to try and clean some bits
of common code up.

This moves to using an array of hw stages for the atoms.
Note this drops the 23 from the vertex shader, this value
is calculated internally when shaders are bound, so not
required here.

This changes the r600 specific GPR adjustment code
to use the stage defines, and arrays.
This is prep work for the tess changes later.

Use NULL tests of the form `if (ptr)' or `if (!ptr)'.
They do not depend on the definition of the symbol NULL.
Further, they provide the opportunity for the accidental

This works when the add also has an immediate. This often happens in
address calculations. These addresses can then be inlined as well.

Even if the rasterizer has scissor disabled, we'll have whatever
vc4->scissor bounds were last set when someone set up a scissor, so we
shouldn't clip to them in that case.
Fixes piglit fbo-blit-rect, and a lot of MSAA tests once they're enabled.
