The only reason why you need a vec4_visitor to construct a
vec4_instruction is to initialize vec4_instruction::ir and
::annotation. Instead set them from vec4_visitor::emit() just like
fs_visitor does.

One should be able to manipulate i965 IR without pulling the whole
FS/VEC4 visitor classes -- Optimization passes and other
transformations would ideally be visitor-agnostic. Among other issues
this avoids a circular dependency between the header file where such
visitor-agnostic code will be defined and the main FS/VEC4 header
where both IR (layer below) and visitor (layer above) happen to be
defined.

Right now virtual GRF book-keeping and allocation is performed in each
visitor class separately (among other hundred different things),
leading to duplicated logic in each visitor and preventing layering as
it forces any code that manipulates i965 IR and needs to allocate
virtual registers to depend on the specific visitor that happens to be
used to translate from GLSL IR.
v2: Use realloc()/free() to allocate VGRF book-keeping arrays (Connor).

Cubemap array images are unlike cubemap array samplers in that they don't need
an additional coordinate to index individual cubemaps in the array, instead
they behave like a 2D array of 6n layers, with n the number of cubemaps in the
array. Take this exception into account.

Some people have complained that code using the CEILING() macro is

The old way made it impossible for the optimizer to reason about what
was going on. The new way is the same number of instructions (the neg
gets folded into the cvt) but enables the optimizer to be cleverer if
comparing to a constant (most common case). [The optimizer is presently
not sufficiently clever to work this out, but it could relatively easily
be made to be. The old way would have required significant complexity to
work out.]
