st/mesa: simplify apply_depthmode()

In preparation for following changes.

I used a temporary test harness to compare the old code to the new
for all possible swizzle inputs.  No change in results.
st/mesa: overhaul texture / sample swizzle code

Previously we only examined the GL_DEPTH_MODE state to determine the
sampler view swizzle for depth textures.  Now we also consider the
texture base format for color textures too.

The basic idea is if we're sampling from a RGB texture we always
want to get A=1, even if the actual hardware format might be RGBA.
We had assumed that the texture's A values were always one since that's
what Mesa's texstore code does.  But if we render to the RGBA texture,
the A values might not be 1.  Subsequent sampling didn't return the
right values.

Now we examine the user-specified texture base format vs. the actual
gallium format to determine the right swizzle.

Fixes several fbo-blending-formats, fbo-clear-formats and fbo-tex-rgbx
failures with VMware/svga driver (and possibly other drivers).
No other piglit regressions with softpipe or VMware/svga.

mesa: fix glMultiDrawArrays inside a display list

The underlying glDrawArrays() calls weren't getting compiled into
the display list.  We simply need to use the current dispatch table
so the CALL_DrawArrays() is routed to the display list save function.

This patch also fixes glMultiModeDrawArraysIBM and
glMultiModeDrawElementsIBM.

Fixes the new piglit gl-1.4-dlist-multidrawarrays test.

freedreno/a3xx: missing wfi

RB_FRAME_BUFFER_DIMENSION is not a banked context register, so we need

not.

freedreno/a3xx/compiler: avoid negative register ids

In some cases, we need a register to be assigned up to three components
before the base.  Since we can't have negative register #'s, just shift
everything up.  May increase register usage for trivial shaders, but I
don't think we are shader limited in those cases.  A proper solution is
going to require a better register assignment algorithm (which is on the
TODO list), this is just a hack to get us by until then.
