The time we want to restrict the Z range of a 3-D surface is when rendering
to it. For storage surfaces, we always want he full range. However, we
still need to set MinimumArrayElement and RenderTargetViewExtent to
sensible values so we'll just set them to the reasonable defaults we used
before we started respecting the base_array_layer and array_len.
This fixes a bunch of Vulkan CTS regressions caused by 48f195d7c6.

Normally, using a non-linear tiling format helps improve cache locality by
ensuring that neighboring pixels are usually close-by in memory. For RGB
formats, this still sort-of holds, but it can also lead to rather terrible
memory access patterns where a single RGB pixel value crosses a tile
boundary and gets split into two pieces in different 4K pages. It also
makes for some rather awkward calculations because your tile size is no
longer an even multiple of surface element size. For these reasons, we
chose to simply never create tiled RGB images in the Vulkan driver.
The GL driver, however, is not so kind so we need to support it somehow. I
briefly toyed with a couple of different schemes but this is the best one I
could come up with. The fundamental problem is that a tile no longer
contains an integer number of surface elements. I briefly considered a
couple other options but found them wanting:
1) Using floats for the logical tile size. This leads to potential
rounding error problems.
2) When presented with a RGB format, just make the tile 3-times as wide.
This isn't so nice because now our tiles are no longer power-of-two
size. Also, it can force the row_pitch to be larger than needed which,
while not strictly a problem for ISL, causes incompatibility problems
with the way the GL driver chooses surface pitches.
The chosen method requires that you pay attention and not just assume that
your tile_info is in the units you think it is. However, it's nice because
it provides a nice "these are the units" declaration in isl_tile_info
itself. Previously, the tile_info wasn't usable as a stand-alone structure
because you had to also know the format. It also forces figuring out how
to deal with inconsistencies between tiling and format back to the caller
which is good because the two different consumers of isl_tile_info really
want to deal with it differently: Computation of the surface size wants
the fewest number of horizontal tiles possible while get_intratile_offset
is far more concerned with things aligning nicely.

The restriction that Y-tiled surfaces must have valign == 4 only aplies to
render targets but we were applying it universally. This causes problems
if ISL_FORMAT_R32G32B32_FLOAT is used because it requires valign == 2; this
should be okay because you can't render to that format.

When Ivy Bridge introduced array multisampling, someone made the decision
to do lots of stuff throughout the driver in terms of physical array layers
rather than logical array layers. In ISL, we use logical array layers most
of the time and it really makes no sense to use physical array layers in
the blorp API. Every time someone passes physical array layers into blorp
for an array multisampled surface, they're always divisible by the number
of samples and we divide right away.
Eventually, I'd like to rework most of the GL driver internals to use
logical array layers but that's going to be a big project and will probably
happen as part of the ISL conversion. For now, we'll do the conversion in
brw_blorp and let blorp just use the logical layers.

The result of this calculation goes into an fma() in the shader and we
would like it to be as precise as possible. The division in particular
was a source of imprecision whenever dst1 - dst0 was not a power of two.

While it can be useful, the field has substantial limtations. In
particular, the bittom 2 or 3 bits is missing so your offset always has to
be a multiple of 4 or 8. While surface alignments usually work out to make
this ok, when you start trying to fake compressed surfaces as uncompressed
(which we will want to do) this falls apart. The easiest solution is to
simply align all offsets to a tile boundary and munge the regions we're
copying to account for the intratile offset.

The convert_to_single_slice operation is *mostly* idempotent. The only
non-repeatable thing it does is that, when it sets the intratile offset
fields, it just overwrites them instead of doing a += operation. This is
supposed to be ok because we have an early return at the top that should
make it bail of the surface is already a single slice. Unfortunately, the
if condition has been broken ever since it was first added in 96fa98c18.
This commit fixes the condition and adds an assert to ensure we don't stomp
any non-zero intratile offsets.

Rather than using platform specific methods to retrieve the program
name pass it explicitly. The function is called directly from main().
Similarly - basename comes in two versions POSIX (can modify string,
always pass a copy) and GNU (never modifies the string).
Just printout the complete program name, esp. since the program is not
meant to be installed. Thus using $basename is unlikely to work, not to
mention it is misleading.
