i965: Override swizzles for integer luminance formats.

The hardware's integer luminance formats are completely unusable;
currently we fall back to RGBA.  This means we need to override
the texture swizzle to obtain the XXX1 values expected for luminance
formats.

Fixes spec/EXT_texture_integer/texwrap formats bordercolor [swizzled]
on Broadwell - 100% of border color tests now pass on Broadwell.

Note: The various O/S functions differ on whether they return the

st/nine: Check for the correct number of constants.

This removes unneeded hack for Anno 1404.
This app is not checking the number of supporting
constants, and rely on the shader compilation to fail
if it puts too many constants.

This patch also checks for the correct number of constants for ps.

Note that we don't check the official limitations for old vs and ps
versions. The restrictions were fixed, unlike for the number of vertex
shader constants for later versions. Likely apps use the correct number,

st/nine: Explicit nine requirements

This patch raises nine requirements and disables nine for old
hw that don't match them.

Currently for these cards only games that don't have tight requirements
would work well with nine. However nine is missing several checks
regarding these limitations.
To make code and future patches less heavy, dropping support for these old
card seems a good solution.

That makes r500 the only dx9 generation cards supported by nine. It seems the one
with the less limitations for nine. Still not everything is ok, and we'll have
for example to implement shader recompilation for these cards to include
integer and boolean constants in the shader.
Eventually when this is done, we can reintroduce support for older cards.
