According to the Sandybridge PRM's description of the resinfo message,
the .z value returned will be Depth == 0 ? 0 : Depth + 1. The earlier
PRMs have the same table.
This means we return 0 for array textures with a single slice, when
we ought to return 1. Just override it to max(depth, 1).

Oddly, this did not affect the shader where I first noticed the pattern.
That particular shader doesn't get its if-statement converted to a bcsel
because there are two assignments in the else-statement. This led to me
submitting https://bugs.freedesktop.org/show_bug.cgi?id=94747.

This fixes a null pointer dereference during the register allocation pass,
if a function had arguments.
Functions arguments get a definition from the function itself, a definition
which is therefore not linked to any instruction. If a value ends up having
a definition but no linked instruction, the register allocation pass doesn't
need to consider whether that value is generated by an instruction that
can only handle "short" registers (on nv50).

Instead of removing every instruction in add_insts_from_block(), just
move the instruction to its scheduled location. This is a step towards
doing both bottom-up and top-down scheduling without conflicts.
Note that this patch changes cycle counts for programs because it begins
including control flow instructions in the estimates.

I think when this code was written, basic blocks were always ended by a
control flow instruction or an end-of-thread message. That's no longer
the case, and removing this restriction actually helps things:

This reverts commit d0e1d6b7e2.
The change in the vec4 code is a mistake -- there's never an
FS_OPCODE_FB_WRITE in vec4 code.
The change in the fs code had the (harmless) effect of not recognizing
an FB_WRITE as a scheduling barrier even if it was marked EOT --
harmless because the scheduler marked the last instruction of a block as
a barrier, something I'm changing in the following patches.
This will be reimplemented later in the series.
All of these were simply code for "architecture register file" (and in
the case of destinations, "not the null register").

This enables in shader defined transform feedback mode even if the
only place xfb_stride is defined is on the global out.
We don't worry about xfb_buffer since Issue 22 c) in the spec says:
"If the shader has an "xfb_buffer" qualifier identifying a buffer,
but doesn't declare "xfb_offset" on anything associated with it,
what happens?
...
variables not qualified with "xfb_offset" are not captured, which
makes the associated "xfb_buffer" qualifier irrelevant."

From the ARB_enhanced_layous spec:
"It is a compile-time or link-time error to have any *xfb_offset*
that overflows *xfb_stride*, whether stated on declarations before

Here we use the built-in validation in
ast_layout_expression::process_qualifier_constant() to check for mismatching
global out strides on buffers in a single shader.
From the ARB_enhanced_layouts spec:
"While *xfb_stride* can be declared multiple times for the same buffer,
it is a compile-time or link-time error to have different values
specified for the stride for the same buffer."
For intrastage validation a new helper link_xfb_stride_layout_qualifiers()
is created. We also take this opportunity to make sure stride is at least
a multiple of 4, we will validate doubles at a later stage.
From the ARB_enhanced_layouts spec:
"If the buffer is capturing any double-typed outputs, the stride must
be a multiple of 8, otherwise it must be a multiple of 4, or a
compile-time or link-time error results."
Finally we update store_tfeedback_info() to apply the strides to
LinkedTransformFeedback and update the buffers bitmask to mark any global
buffers with a stride as active. For example a shader with:
layout (xfb_buffer = 0, xfb_offset = 0) out vec4 gs_fs;
layout (xfb_buffer = 1, xfb_stride = 64) out;
Is expected to have a buffer bound to both 0 and 1.
From the ARB_enhanced_layouts spec:
"A binding point requires a bound buffer object if and only if its
associated stride in the program object used for transform feedback
primitive capture is non-zero."

This allows us to print the correct binding point when not all
