vbo: improve the code style by adjust the preprocessing c code directives
Brian Paul review suggestion: there's more macro use here than necessary.
Removed and redefine some #define preprocessing directives.
Removed the directive input parameter 'T' .
No functional changes.

i965: Fix out-of-bounds accesses into pull_constant_loc array
The piglit test glsl-fs-uniform-array-loop-unroll.shader_test was designed
to do an out of bounds access into an uniform array to make sure that we
handle that situation gracefully inside the driver, however, as Ken describes
in bug 79202, Valgrind reports that this is leading to an out-of-bounds access
in fs_visitor::demote_pull_constants().
Before accessing the pull_constant_loc array we should make sure that
the uniform we are trying to access is valid.

i965/hiz: Start to separate miptree out from hiz buffers
Today we allocate a miptree's for the hiz buffer. We needed this in
the past because we would point the hardware at offsets of the hiz
buffer. Since the hiz format is not documented, this is not a good
idea.
Since moving to support layered rendering on Gen7+, we no longer point
at an offset into the buffer on Gen7+.
Therefore, to support hiz on Gen7+, we don't need a full miptree
structure allocated.
This patch starts to create a new auxiliary buffer structure
(intel_miptree_aux_buffer) that can be a more simplistic miptree
side-band buffer associated with a miptree. (For example, to serve the
needs of the hiz buffer.)

i965/fs: Don't issue FB writes for bound but unwritten color targets.
We used to loop over all color attachments, and emit FB writes for each
one, even if the shader didn't write to a corresponding output variable.
Those color attachments would be filled with garbage (undefined values).
Football Manager binds a framebuffer with 4 color attachments, but draws
to it using a shader that only writes to gl_FragData[0..2]. This meant
that color attachment 3 would be filled with garbage, resulting in
rendering artifacts. Now we skip writing to it, fixing rendering.
Writes to gl_FragColor initialize outputs[0..nr_color_regions-1] to
GRFs, while writes to gl_FragData[i] initialize outputs[i].

i965/fs: Make emit_shader_time_end() insert before EOT.
Previously, we emitted the shader-time epilogue from emit_fb_writes(),
during the middle of looping through color regions (or emit_urb_writes
for the VS). This is duplicated several times and rather awkward.
I need to fix a bug in our FB write handling, and it will be a lot
easier if we move emit_shader_time_end() out of there.
Now, we simply emit FB writes/URB writes, and subsequently have
emit_shader_time_end() insert instructions before the final SEND with
EOT. Not only is this simpler, it's actually a slight improvement:
we now include the MOVs to set up the final FB write payload in our
shader-time measurements.
Note that INTEL_DEBUG=shader_time only exists on Gen7+, and uses
send-from-GRF. (In the past, we might have hit trouble where both
attempt to use MRFs for messages; that's not a problem now.)
