mesa: Add an implementation of a master convert function.

v2 by Iago Toral <itoral@igalia.com>:

- When testing if we can directly pack we should use the src format to check
  if we are packing from an RGBA format. The original code used the dst format
  for the ubyte case by mistake.
- Fixed incorrect number of bits for dst, it was computed using the src format
  instead of the dst format.
- If the dst format is an array format, check if it is signed. We were only
  checking this for the case where it was not an array format, but we need
  to know this in both scenarios.
- Fixed incorrect swizzle transform for the cases where we convert between
  array formats.
- Compute is_signed and bits only once and for the dst format. We were
  computing these for the src format too but they were overwritten by the
  dst values immediately after.
- Be more careful when selecting the integer path. Specifically, check that
  both src and dst are integer types. Checking only one of them should suffice
  since OpenGL does not allow conversions between normalized and integer types,
  but putting extra care here makes sense and also makes the actual requirements
  for this path more clear.
- The format argument for pack functions is the destination format we are
  packing to, not the source format (which has to be RGBA).
- Expose RGBA8888_* to other files. These will come in handy when in need to
  test if a given array format is RGBA or in need to pass RGBA formats to

mesa: Let _mesa_get_format_base_format also handle mesa_array_format.

If we need the base format for a mesa_array_format we have to find the
matching mesa_format first. This is expensive because it requires
to loop through all existing mesa formats until we find the right match.

We can resolve the base format of an array format directly by looking
at its swizzle information. Also, we can have _mesa_get_format_base_format
accept an uint32_t which can pack either a mesa_format or a mesa_array_format

check if they have a mesa_format or a mesa_array_format and call different
functions depending on the case.

Another reason to resolve the base format for array formats directly is that
we don't have matching mesa_format enums for every possible array format, so
for some GL format/type combinations we can produce array formats that don't
have a corresponding mesa format, in which case we would not be able to
find the base format. Example format=GL_RGB, type=GL_UNSIGNED_SHORT. This type

i965: Respect the no_8 flag on Gen6, not just Gen7+.

When doing repclears, we only want to use the SIMD16 program, not the
SIMD8 one.  Kristian added this to the Gen7+ code, but apparently we
missed it in the Gen6 code.  This patch copies that code over.

Approximately doubles the performance in a clear microbenchmark from

In implementing ARB_DIRECT_STATE_ACCESS functions, it is often necessary to
abstract the functionality of a traditional GL API function into a backend
that both the traditional and dsa API functions can share.  For instance,
glTexParameteri and glTextureParameteri both call _mesa_texture_parameteri,
which takes a context object and a texture object as arguments.

The existance of such backend functions provides the opportunity for
driver internals (such as meta) to pass around the actual texture object
rather than its ID or target, saving on texture object storage and look-up
overhead.

function _mesa_texture_storage that takes a context and a texture object as

it and avoid looking up the context and the texture object.  However, backend
names often look very close to the names of software fallbacks (ie.

freedreno/ir3: simplify RA

Group inputs/outputs, in addition to fanin/fanout, as they must also
exist in sequential scalar registers.  This lets us simplify RA by
working in terms of neighbor groups.

NOTE: has the slight problem that it can't optimize out mov's for things
like:

  MOV OUT[n], IN[m]

To avoid this, instead of trying to figure out what mov's we can
eliminate, we first remove all mov's prior to grouping, and then
re-insert mov's as needed while grouping inputs/outputs/fanins.
Eventually we'd prefer the frontend to not insert extra mov's in the
first place (so we don't have to bother removing them).  This is the
plan for an eventual NIR based frontend, so separate out the instr
grouping (which will still be needed for NIR frontend) from the mov
elimination (which won't).
