try_rewrite_rhs_to_dst is a quick optimization to avoid generating new
temporaries (and MOVs from those temporaries to the dest) for every
expression tree we visit. By generating better code in simple cases, we
reduce the burden on later optimization passes like register coalescing.
Previously, we compared inst->regs_written() to lhs->vector_elements
to make sure the instruction generating our value wrote the same number
of components as our destination register.
However, this fails in some cases. One example is texturing (which
produces a vec4) into gl_FragData[i]. Technically, gl_FragData[i] is
also a vec4. However, the destination VGRF actually has size 4n (where
n is the size of the array).
split_virtual_grfs() can't split VGRFs that are used by SEND messages
which require contiguous destination registers (like texturing), and
register allocation needs all VGRFs to have sizes between 1 and 4.
Amnesia: The Dark Descent hits this case: a texturing instruction
(4 components) gets rewritten to the gl_FragData output register
(which was 4*3 = 12 components), causing the register allocator to
hit the "we rely on split_virtual_grfs" assertion.
This makes it possible to play Amnesia.

Fetch shaders are usually destroyed at the context destruction by the state
tracker, so we can put them all in a large buffer without wasting memory.
This reduces the number of relocations sent to the kernel a little bit.

The face direction stuff is also a bit messy, I've no idea if that could

Before this we only supported user-based constant buffers.
First, we basically plumb pipe_constant_buffer objects through llvmpipe
rather than pipe_resource objects.
Second, update llvmpipe_set_constant_buffer() and try_update_scene_state()
so they understand both resource- and user-based constant buffers.
The problem with user constant buffers is the potential for use-after-free,
as seen in some WebGL tests. The next patch will flip the switch for
resource-based const buffers.

I had tried this in the past, but ran into trouble with applications
that sample from undiscarded pixels in the same subspan. To fix that
issue, only jump to the end for an entire subspan at a time.

HALT until gen6.
