gallium: Replace texture target with resource operand in TGSI texture opcodes.

Instead of specifying a texture target for texture instructions:

  TEX OUT[0], IN[0], SAMP[0], 2D

one declares a resource register and then uses it to access textures:

  DCL RES[0], 2D
  ...
  TEX OUT[0], RES[0], IN[0], SAMP[0]

The resource index (not sampler index) is used to select a texture
to be accessed. Texture target is taken from resource's declaration.

This change allows us to separate samplers from textures, something
that is needed by OpenCL.

Fixed most of the tree, didn't compile-test gallium drivers. The 965
driver hasn't been touched at all -- will need help fixing that one.
