[Mesa-dev] [PATCH 03/14] gallium: Introduce 32-bit packed format names

[Adam Jackson]

From: Richard Sandiford <r.sandiford at uk.ibm.com>

These are for interacting with buffers natively described in terms of
bit shifts, like X11 visuals:

    uint32_t xyzw8888 = (x << 0) | (y << 8) | (z << 16) | (w << 24);

Define these in terms of (endian-dependent) aliases to the array-style
format names.
