This fixes a wine test and some minor visual issues on some games.
The patch is not optimal, there is probably a more efficient way to
fix this issue, but the code there already has some innefficiencies.
There is plans to rewrite that part of the code to make it more
efficient.

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,
and it's not a problem for us if it wants use more.

r500 hasn't enough float constants for vs to fill all needs.
Overlapping issues can happen with complex shaders.
The fix would be to recompile shaders to include the integer
and boolean constants, instead of reserving slots for them.

Previously 276 constants were declared everytime.
This patch makes shaders declare constants up to the maximum
constant needed and moves the moment we print the TGSI
shader after the moment we declare the constants.
This is needed for r500, since when indirect addressing is used,
it cannot reduce the amount of constants needed, and that it is
restricted to 256 constant slots.

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.

Resolving a multisampled depth texture into
a single sampled texture is supported on >= SM4.1
hw. It is possible some previous hw support it.
The ability was tested on radeonsi and nvc0.
Apparently is is also supported for radeon >= r700.
This patch adds the MULTISAMPLE_Z_RESOLVE cap and
add it to the drivers. It is advertised for drivers
for which it is sure the ability is supported.

Even though llvmpipe copies constant (ie uniform) buffers internally, the

As ffsll doesn't exist in MSVC yet, and u_bit_scan64 is only used by
radeonsi which is never built with MSVC.
This is just a stop-gap fix to unbreak MSVC build until we refactor these
mathematical portability wrappers into src/util.
Trivial.
We need a slot for the stipple texture and the pixel shader already uses
32 textures (16 API slots + 16 FMASK slots).

Originally, get_alu_src was supposed to handle resolving swizzles and
things like that. However, now that basically every instruction we have
only takes scalar sources, we don't really need it anymore. The only case
where it's still marginally useful is for the mov and vecN operations that
are left over from SSA form. We can handle those cases as a special case
easily enough. As a side-effect, we don't need the vec_to_movs pass
anymore.
