This test file is very similar to test 113-line-and-file-macros but uses token
pasting for cleaner quiz answers (without spaces between the digits). This
test passes thanks to the recent addition of support for pasting INTEGER
tokens, (but would have failed without that).
(Note that this test is distinct from test 059-token-pasting-integer which
pastes integers parsed from the source. Those are parsed to INTEGER_STRING
tokens and are already pasted correctly as verified by that test. The only way
to generate the INTEGER tokens which currently fail to paste is with an
internal define such as __LINE__ that results in an integer.)

As recently tested in the additions to the invalid paste test, it is illegal
to paste a non-digit sequence onto the end of an integer.
The 082-invalid-paste test should now pass again.

These tokens are easy to expand by just looking at the current, tracked
location values, (and no need to look anything up in the hash table).
Add a test which verifies __LINE__ with several values, (and verifies __FILE__
for the single value of 0). Our testing framework isn't sophisticated enough
here to have a test with multiple file inputs.

Support 1d and 2d array textures (including shadow samplers),
and (as a side effect mostly) also shadow cube samplers.
Seems to pass the relevant piglit tests both for sampling and rendering
to (though some require version overrides).
Since we don't support render target indices rendering to array textures
is still restricted to a single layer at a time.
Also, the min/max layer in the sampler view (which is unnecessary for GL)
is ignored (always use all layers).

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.

Compiling shaders requires several main steps:
1. Generating VS 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 "vec4_generator."
There are several reasons for doing so:
1. Future hardware has a different instruction encoding. Splitting
this out will allow us to replace vec4_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 vec4_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
vec4_visitor and create IR, while ADD() in vec4_generator() can
create brw_instructions. (Patches for this upcoming.)

The brw_compile structure is closely tied to the Gen4-7 hardware
encoding. However, do_vs_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.

During compilation, we allocate a bunch of things: the IR needs to last
at least until code generation...and then the program store needs to
last until after we upload the program.
For simplicity's sake, just keep it all around until we upload the
program. After that, it can all be freed.
This will also save a lot of headaches during the upcoming refactoring.
