Boolean are used for if/then/else and Integer constants

The compilers can generate better code if these values are known

I haven't met so far a game that would change the values of these
constants frequently (and when they do, they set to the values used
for the previous draw call, and thus the changes get filtered out).

Thus it makes sense to inline these constants and recompile the shaders.
The commit sets a bound to the number of variants for a given shader
to avoid too many shaders to be generated.

One drawback is it means more shader compilations. It would probably

st/nine: Finish if nooverwrite after normal mapping

d3d's nooverwrite and gallium's unsynchronized
have different semantics.
Indeed nooverwrite says the applications won't
write to locations needed by previous draws,
which is less strong than unsynchronized which
won't synchronize previous writes.

Thus in case app is locking without discard/nooverwrite,
then using nooverwrite, we need to add a
synchronization.

st/nine: Fix buffer/texture unbinding in nine_state_clear

Previously nine_state_clear was not using
NineBindBufferToDevice and NineBindTextureToDevice
to unbind buffers and textures (but used nine_bind)

This was resulting in an uncorrect bind count for these
resources.

Combined with
0ec4e5f630ed68ece3f176b174cfd66eff023904
Some buffers were scheduled to be uploaded directly
after they were locked (because the bind count incorrectly
assumed they were needed for the next draw call),
which resulted in uploads before the data was written.

To simplify a bit the code (and because I needed to
add a pointer to device),
remove the stateblock usage from nine_state_clear and
rename to nine_device_state_clear.

iris: Use the linear version of the surface format during fast clears.

Newer gens (> 9) will start doing the linear -> sRGB conversion of the
clear color for us, if we use a sRGB surface format. So let's make sure
that doesn't happen and keep the same semantics as before.

Even though the hardware could convert the clear color for us during
fast clear, that converted color is only used for sampling. For resolve,
the original color would be used (without the conversion). So we convert
it ourselves and the same converted color gets used for both sampling
and resolving, simplifying the whole logic.

iris: Support sRGB fast clears even if the colorspaces differ.

We were disabling fast clears if the view format had a different
colorspace than the resource format (sRGB vs linear or vice-versa). But
we actually support them if we use the view format to decide if we
should encode the clear color into sRGB colorspace.

Also add a missing linear -> sRGB surface format conversion (we don't
want the clear color to be encoded to sRGB again during resolve).

v2: Do not track sRGB colorspace during fast clears (Nanley).
