The patch that follows will move the definition of struct
brw_vec4_prog_key from brw_vs.h to brw_vec4.h, making it necessary for
brw_vs.h to include brw_vec4.h (because brw_vs.h defines struct
brw_vs_prog_key, which contains brw_vec4_prog_key as a member). Since
brw_vs.h is included from C source files, that means that brw_vec4.h
will need to be safe to include from C. Same for brw_shader.h, since
it is included by brw_vec4.h.

This makes brw_context inherit directly from gl_context; that was the
only thing left in intel_context.

I need this so I can look at vec4 and fs registers' files from the same
.cpp file without namespaces. As far as I can tell we never rely on the
particular numerical values of the files, though I thought it sounded like
a good idea when doing the VS (it turns out having 0 be BAD_FILE is nicer).

These are entirely based on the opcode, which is available in
backend_instruction. It makes sense to only implement them in one
place.
This changes the VS implementation of is_tex() slightly, which now
accepts FS_OPCODE_TXB and SHADER_OPCODE_LOD. However, since those
aren't generated in the VS anyway, it should be fine.
This also makes is_control_flow() available in the VS.

The next patch is going to change the type of vec4_visitor::vp from
struct gl_vertex_program * to struct gl_program *, and rename it. The
sensible name to change it to is vec4_visitor::prog. However, prog is
already used in backend_visitor (which vec4_visitor derives from).
Since backend_visitor::prog is of type struct gl_shader_program *, it
makes sense to rename it to shader_prog.

I'd previously added the minimum names to understand my dumps, but this
makes dumps in general much easier to read.

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.

Note that BRW_PREDICATE_NONE is 0 and BRW_PREDICATE_NORMAL is 1, so that's a
lot like the true/false we had in the FS before.

This will let us reuse brw_fs_cfg.cpp from brw_vec4_*.

We'll want to reuse this for the VS, and it's complex enough that I'd
rather not cut and paste it.

The low-level IR is a mashup of brw_fs.cpp and ir_to_mesa.cpp. It's
currently controlled by the INTEL_NEW_VS=1 environment variable, and
only tested for the trivial "gl_Position = gl_Vertex;" shader so far.

This should make gdbing more pleasant, and it might be used in sharing
part of the codegen between the VS and FS backends.

These will be used by the VS backend as well.
