In the first pass of implementing exact handling, I made a mistake with
search-and-replace. In particular, we only reallly handled exact/inexact
on the root of the tree. Instead, we need to check every node in the tree
for an exact/inexact match. As an example of this, consider the following
GLSL code
precise float a = b + c;
if (a < 0) {
do_stuff();
}
In that case, only the add will be declared "exact" and an expression that
looks for "b + c < 0" will still match and replace it with "b < -c" which
may yield different results. The solution is to simply bail if any of the
values are exact when matching an inexact expression.
Found with grep and inspection. Test compiled on RPi hw.
Assists any future effort to remove TGSI as an intermediate stage.

Meaning, always rebuild them when asked instead of bothering to look at

glapi: glX_proto_size.py: use argparse instead of getopt
Which changed most, but not all, callers to use --header-tag instead of
-h.

We disable the vertex attributes, but also disable the VBO fetch details
as well, just in case. Not known to fix anything.

Back in the dawn of time, we used to do immediate uploads for the vertex
data, and all was well. However Maxwell dropped support for immediate
vertex data, so we started feeding in a VBO (in all cases). But we
forgot to disable some things that apply in such cases, specifically
primitive restart and index bias. The latter was causing WoW and other
Blizzard games trouble as they use a pattern where they draw with a base
vertex (aka index bias), followed by texture uploads (aka blits,
internally).

On Fermi, there's an argument in front of the coords that combines array
and indirect handle, while on Kepler the array and the indirect handle
are separate (and in front of the coords). We were previously only
accounting for the array bit of it, if there were an indirect access it
wouldn't be counted in the formula.

Apparently there's no post-FS clamping logic, so we have to do this by
hand. The depth will never be outside of the 0..1 range, even on
floating point zeta buffers, so this should be safe.
Fixes dEQP-GLES3.functional.fbo.depth.*clamp.* which tests writing
invalid values on various zeta buffer formats.

The st_texture_object documentation says:
"the number of 1D array layers will be in height0"
We can't minify that.
Spotted by luck. No app is known to hit this issue.

This is required to create multiple, horizontally adjacent, max-width
images from one blit2d surface. This is also required for more accurate
width specification of surfaces within a larger surface (which is seen
as the smaller surface's enclosing region).

This reduces some of the craziness required for handling buffer
blocks. The problem is each shader stage holds its own information
about a block in memory, we were copying that information to a
program wide list but the per stage information remained meaning
when a binding was updated we needed to update all versions of it.
This changes the per stage blocks to instead point to a single
version of the block information in the program list.
