OpenGL allows you to declare user-defined fragment shader outputs with
less than four components:
out ivec2 color;
This makes sense if you're rendering to an RG format render target.
Previously, we assumed that all color outputs had four components (like
the built-in gl_FragColor/gl_FragData variables). This caused us to
call emit_color_write for invalid indices, incrementing the output
virtual GRF's reg_offset beyond the size of the register.
This caused cascading failures: split_virtual_grfs would allocate new
size-1 registers based on the virtual GRF size, but then proceed to
rewrite the out-of-bounds accesses assuming that it had allocated enough
new (contiguously numbered) registers. This resulted in instructions
that accessed size-1 GRFs which register numbers beyond
virtual_grf_next (i.e. registers that were never allocated).
Finally, this manifested as live variable analysis and instruction
scheduling accessing their temporary array with an out of bounds index
(as they're all sized based on virtual_grf_next), and the program would
segfault.
It looks like the hardware's Render Target Write message requires you to
send four components, even for RT formats such as RG or RGB. This patch
continues to use all four MRFs, but doesn't bother to fill any data for
the last few, which should be unused.

Commit 0c005bd7 intended to make ir_loop_jump::mode public, but also
accidentally added a new pointer to the enclosing loop. Furthermore, it
tried to initialize the new field by adding "this->loop = loop;" to the
constructor, but since there is no loop parameter, this only initialized
the field to itself---so it will likely be a garbage pointer.
A lot of code, such as lower_jumps, allocates new loop jumps without
setting this field appropriately, so any uses would probably just crash.
Thankfully, there were none, so we can just delete the field.
