intel: Remove our custom _mesa_store_compressed_texsubimage2d().

Now that Mesa core knows how to map teximages, we no longer needed the

In Android a native window has a queue of back buffers allocated by the

  dequeue the next back buffer

  enqueue the buffer

After enqueuing, the buffer is no longer valid to EGL.  A window has no

EGL.

Signed-off-by: Dave Airlie <airlied@redhat.com>

i915g: Fix off-by-one in scissors.

i915g: Fix case where texcoords can overlap with fragpos/frontface.

i915g: Improve the flush heuristic by using the previous frame's number of vertices.

r600g: fix replace_gpr_with_pv_ps

Instructions with 3 source operands have no write mask, so we may replace their
destinations with PV/PS in the next group even if their dst.write is 0.

Note: This is a candidate for the 7.11 branch.

r600g: fix check_and_set_bank_swizzle

Need to do full check when not all bank swizzles in the group are forced
(e.g. when trying to merge interp_* group with the next instruction)

Note: This is a candidate for the 7.11 branch.

i965: Remove all bits of NRM3 and NRM4 code

Nothing in Mesa generates these opcodes, and i965 hardware cannot
support it natively.  If support were ever added for this opcode in
Mesa, there had better be a lowering pass for hardware that doesn't
support it natively.

glsl: fix crash when a const is passed to texelFetchOffset

glsl: Bail after reporting an error for non-constant const_in parameters.

Otherwise we continue and hit the "Illegal formal parameter mode"
assertion.

This adds texelFetch support to translate from GLSL to TGSI TXF opcode.

I've tested this works with an r600g and softpipe backend.

softpipe: implement TXF support via get_texel callback

This just calls the texel fetch functions directly bypassing the sampling,

notes:
1: loops inside switch should be more optimal.
2: borders can be sampled though only up to border depth, outside that
its undefined.

tgsi: add TXF support.

This is a straight texel fetch with no filtering or clamping. It uses
integers to specify the i/j/k (from EXT_gpu_shader4).

To enable this I had to add another hook into the tgsi sampler so that
we could easily bypass all the filtering sample does.
