[PATCH 0/1] MR264: vkd3d-shader/ir: Rename vkd3d_shader_instruction to ir_instr.

[Zebediah Figura (＠zfigura)]

There are a few motivations for this:

* Identifiers beginning with vkd3d_shader_ look like external API. Changing the
  prefix makes it clear that this is an internal API.

* vkd3d_shader is a very long prefix, which is annoying to type [not least
  because "vkd3d" itself is an unwieldy name.] This is also a motivation for
  shortening "instruction" to "instr".

* The "vkd3d_instruction" is increasingly growing from a simple parsed
  representation of sm4 bytecode, to a proper IR in its own right—e.g. we are
  using it for sm1 and sm6, are performing passes over it, and we have plans to
  extend its scope further, e.g. to HLSL compilation. Give it a name that
  reflects and clearly communicates what it is.

Waiting for bikeshedding :D

There are a few ideas for the name of this "component":

- "ir", as this patch, which I chose because it matches the file name. This is a
  bit questionable since it's unspecific/ambiguous (and we already have at least
  one other IR), but on the other hand, this is intended to be "the" IR of
  vkd3d-shader.

- "vsir", an abbreviation of the obvious "vkd3d-shader IR"

- "vazir", a bit more of a creative/clever name, since I personally like those;
  Persian for "minister" but which I understand can also mean something close to
  "helper" or "assistant", which seems quite fitting. (I've tried to also make it
  into an acronym but the 'z' makes things difficult.)

- "shader", i.e. remove the "vkd3d_" prefix. This is kind of done in some places
  already. I feel kind of lukewarm about this personally, on the grounds that
  it's (a) doesn't look like a component name, and (b) doesn't have "ir" in it
  (whereas I think it's clear that what we're dealing with is an IR).
