Add a BlockHandler which flushes the context and reports the dirty region
gathered using the X server damage layer.
In the interim, with dirty region reporting only allocate textures for the
framebuffer and shared pixmaps (e.g. DRI2 buffers) and fall back to software
for other pixmaps. This will be improved in the future.
When a single-buffered window was resized the new window size was never
detected. This fix that, but there's still a bug which causes window
contents corruption for certain window sizes...

When translating an incoming shader (rather than building one from scratch)
it's preferable to be able to call a single, generic instruction emitter
rather than figuring out which of the opcode-specific functions to call.
Part of this code is disabled since no performance gains
where detected with it enabled.
This code only detects if it is a pixmap that it is
rendering to on the st/xorg DDX since it sets the fake
front to the same handle as front.
SOA dependencies can happen when a register is used both as a source and
destination and the source is swizzled. For example:
MOV T, T.yxwz; would expand into:
MOV t0, t1;
MOV t1, t0;
MOV t2, t3;
MOV t3, t2;
The second instruction will produce the wrong result since we wrote to t0
in the first instruction. We need to use an intermediate temporary to fix
this.
This will take more work to fix for all TGSI instructions. This seems to
happen with MOV instructions more than anything else so fix that case now
and warn on others.
Fixes piglit glsl-vs-loop test (when not using SSE). See bug 23317.
