gallium: move clear paths from rgba to a pointer to a color union (v2)
This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values.
Notes:
1. the value is opaque.
2. only when the value is used should it be interpretered according to
the surface format it is going to be used with.
3. float clears on integer buffers and vice-versa are undefined.
v2: fixed up vega and graw, dropped hunks that shouldn't have been in
patch.

Pass an explicit surface format as we do with pipe_put_tile_rgba_format().
This fixes the piglit fbo-srgb-blit test. With GL_EXT_framebuffer_sRGB we
override the resource's format with an explicit format (linear vs. sRGB).
We need to do so both when getting and putting tiles.

r600g: take constantly interpolated values into a/c
We could constant interpolated values now and set have_perspective
if nothing else is set to avoid a GPU hang.

TGSI CONSTANT interpolation is just flat, and we just read the values
direct from the LDS into the GPR without doing any interpolation on them.
This is needed to pass integer types into the fragment shader.

r600g: set number type correctly for color buffers.
If we get a scaled type assume its a real integer type (as textures are).
Also fixup the blend bypass and blend clamp flags on evergreen as per the
docs.

softpipe: fix blending for luminance/intensity surfaces
If we're drawing to a luminance, luminance/alpha or intensity surface
we have to adjust (rebase) the fragment/quad colors before writing them
to the tile cache. The tile cache always stores RGBA colors but if
we're caching a L/A surface (for example) we need to be sure that R=G=B
so that subsequent reads from the surface cache appear to return L/A
We previously had a special case for RGB (no alpha) surfaces. This
change generalizes that for the other base formats.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=40408, but sRGB
formats are still failing. That'll be addressed in a later patch.

Also includes loading of shared shader library code (used for f64
and integer division) and setting up the immediate array buffer
which is appended to the code.
Per the GL spec, clamp incoming colors prior to blending depending on
whether the destination buffer stores normalized (non-float) values.
Note that the constant blend color needs to be clamped too (we always
get the unclamped color from Mesa).
