radeonsi: Implement ddx/ddy on VI using ds_bpermute

The ds_bpermute instruction allows threads to transfer data directly
to or from the vgprs of other threads.  These instructions use the LDS
hardware to transfer data, but do not read or write LDS memory.

i965: Fix clear code for ignoring colormask for XRGB formats on Gen9+.

In commit cda886a4851ab767fba40e8474d6fa8190347e4f, Neil made us stop
advertising RGBX formats on Gen9+, as the hardware apparently no longer
has working fast clear support for those formats.  Instead, we just
fall back to RGBA formats, and use SCS to override alpha to 1.0.

This is fine, but had one unintended side effect: it made us fall back
to slow clears when the color mask disables alpha.  Normally, we ignore
the color mask for non-existent channels.  This includes alpha for XRGB
formats as writing garbage to the X channel is harmless.  But, now that
we use RGBA, we think there's a real alpha channel, and can't do the
optimization.

To hack around this, check if _BaseFormat is GL_RGB and ignore alpha.

i965/blorp: Improve precission of blitting coordinates when clipping

We do this in two steps: first we clip the dst rect and adjust the src
rect accordingly. Then we do it the other way around. In both passes
the adjustment part involves multiplying by a scale factor that can lead
to a small precision loss. This is breaking a few dEQP tests.

Specifically, the problem happens when we need to clip the same coordinate
twice. For example, if srcX0 and dstX0 need both to be clipped we want to
avoid the situation where we clip srcX0 first, then adjust dstX0 accordingly
but then we realize that the resulting dstX0 still needs to be clipped, so
we clip dstX0 and adjust srcX0 again. Each of these two passes can lead
to precission loss. What we want to do here is detect the rect that leads
to the largest clip (accounting for the scale factor involved), clip that
rect and adjust the other one. With this we ensure that the adjusted
coordinate does not need to be clipped again and we can skip a second pass,
improving precision.

Fixes the following 4 dEQP tests:

glsl: Relax GLSL 1.10 float suffix error to a warning.

Float suffixes are allowed in all subsequent GLSL specifications, and
it's obvious what the user meant if they specify one. Accept it with a
warning to avoid breaking applications, like Planeshift (although it
looks like between 0.6.1 and 0.6.3 they might have removed the suffixes
from their shaders).

i965/fs: Readd opt_drop_redundant_mov_to_flags().

This reverts commit b449366587b5f3f64c6fb45fe22c39e4bc8a4309.

I removed the pass thinking that it was now not useful, but that was not
true. I believe I ran shader-db on HSW and saw no results, but HSW does
not use the unlit centroid workaround code and as a result does not emit
redundant MOV_DISPATCH_TO_FLAGS instructions.

On IVB, the shader-db results are:

total instructions in shared programs: 6650806 -> 6646303 (-0.07%)
