cont -> skip, last -> kill, and fix the special case handling. It's just an
enum. Makes the disassembly easier to read and closer to Bifrost.

Helpful to disable the scheduler when debugging, so the assembly can be
compared against the NIR directly when lost in a big dEQP test.

Implements load store opreations as midgard_op_ld_image_* and
midgard_op_st_image_*.
Implements midgard_op_lea_tex, which takes an image coordinate and
returns it's memory address.
Image atomics are implemented as a combination of midgard_op_lea_tex and
the usual midgard atomic opcodes.
Currently we don't support multisampled shader images.

By applying `textureGather` to a `sampler2DShadow`, the blob produces
(under the old disassembly):
tex_22.vtx.2d.shadow.cont.last r29, texture0, fsampler0.zwyx, r29,
The op 0x22 is 10|0010 in binary, the old shadow parameter is 1, and old
gather parameter is 0, so we get 0110|0010 in binary, or an op of
textureLod with a mod of 0110 = 6.

We reduce the op to 4-bits, such that the derivative mode becomes its
own adjacent parameter. This cleans up handling of texture gathers, but
does not affect functionality.

Each instruction bundle can contain up to 16 constant bytes. The meaning
of those byte is instruction dependent: it depends on the instruction
native type (int, uint or float) and the instruction reg_mode (8, 16, 32
or 64 bit). Those different layouts can be exposed as a union to
facilitate constants manipulation.

My latest divination spell has uncovered a pattern in the aether.
Although the swizzle is unaligned, its format is otherwise standard.
Document this, removing the old incorrect understanding of the swizzle
(which coincided on common special swizzles only).
