This partially reverts commit 7bba4879bb, but

Traditionally, OpenGL has had two separate equations for converting from
signed normalized fixed-point data to floating point data. One was used
primarily for vertex data, while the other was primarily for texturing
and framebuffer data.
However, ES 3.0 and GL 4.2 change this, declaring there's only one
equation to be used in all cases. Unfortunately, it's the other one.
v2: Correctly convert 0b10 to -1.0, as pointed out by Chris Forbes.

The brw_compile structure contains the brw_instruction store and the
brw_eu_emit.c state tracking fields. These are only useful for the
final assembly generation pass; the earlier compilation stages doesn't
need them.
This also means that the code generator for future hardware won't have
access to the brw_compile structure, which is extremely desirable
because it prevents accidental generation of Gen4-7 code.
v2: rzalloc p, as suggested by Eric.

Compiling shaders requires several main steps:
1. Generating FS IR from either GLSL IR or Mesa IR
2. Optimizing the IR
3. Register allocation
4. Generating assembly code
This patch splits out step 4 into a separate class named "fs_generator."
There are several reasons for doing so:
1. Future hardware has a different instruction encoding. Splitting
this out will allow us to replace fs_generator (which relies
heavily on the brw_eu_emit.c code and struct brw_instruction) with
a new code generator that writes the new format.
2. It reduces the size of the fs_visitor monolith. (Arguably, a lot
more should be split out, but that's left for "future work.")
3. Separate namespaces allow us to make helper functions for
generating instructions in both classes: ADD() can exist in
fs_visitor and create IR, while ADD() in fs_generator() can
create brw_instructions. (Patches for this upcoming.)
Furthermore, this patch changes the order of operations slightly.
Rather than doing steps 1-4 for SIMD8, then 1-4 for SIMD16, we now:
- Do steps 1-3 for SIMD8, then repeat 1-3 for SIMD16
- Generate final assembly code for both modes together
This is because the frontend work can be done independently, but final
assembly generation needs to pack both into a single program store to
feed the GPU.

Final code generation should never fail. This is a bug, and there

Also, we're not going to have a fail() method in a moment.

The brw_compile structure is closely tied to the Gen4-7 hardware
encoding. However, do_wm_prog is very generic: it just calls out to
get a compiled program and then uploads it.
This isn't ultimately where we want it, but it's a step in the right
direction: it's now closer to the code generator.

No longer have to split fetching into quads dynamically if mip levels

This also adds some code to handle per-quad lods for more than 4-wide fetches,
because otherwise I'd have to integrate the texelFetch function into
the splitting stuff... (but it is not used yet outside texelFetch).

a test error (results are undefined for out-of-bounds fetches, we return
whatever is at offset 0, whereas the test expects [0,0,0,1]).
Texel offsets are only handled by texelFetch for now, though the interface
can handle it for everything.
