i965/fs: Revert "Avoid generating MOVs for assignments for expressions."

This reverts commit 53c89c67f33639afef951e178f93f4e29acc5d53, along with
the subsequent this->result = reg_undef additions it required.

Both Eric and I agree that the way he did this is really fragile; if you
forget to add this->result = reg_undef before calling accept(), it may
end up using the same register for two separate things, breaking things
in strange and mysterious ways.

The next commit will port over the new VS backend's method for solving
this problem, which is simpler, less intrusive, and still manages to
avoid MOVs in the common case.

mesa: Remove all mention of MESA_FORMAT_CI8

Nothing in Mesa supports color-index textures, and most of the other
infrastructure that could allow such support has already been removed.
This puts the final nail in the coffin.

Also clean out some GL_COLOR_INDEX comments in formats.c.

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

After enqueuing, the buffer is no longer valid to EGL.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

i965: Remove all bits of NRM3 and NRM4 code

Nothing in Mesa generates these opcodes, and i965 hardware cannot

Mesa, there had better be a lowering pass for hardware that doesn't
