Bug found by the liveness analysis validation pass that will be
introduced in a later commit. The no-op MOV check in
opt_register_coalesce() was removing instructions which makes the
cached liveness analysis calculation inconsistent with the shader IR.
We were failing to set progress to true in that case though, which
means that invalidate_live_intervals() wouldn't necessarily be called
at the end of the function.

When reading the source code, it's useful to indicate that a group of
fields in a struct are related in someway. There were several places
where people tried to group related structure members with the {@
syntax, without realizing they also needed to add the \name syntax in
order to generate correct doxygen html.
There are several files with groupings that look like this:
struct foo {
/**
* Related fields description
* @{
*/
int bar;
char baz;
/** @} */
long qux;
}
However, the doxygen syntax for grouping is:
struct foo {
/**
* \name Related fields description
* @{
*/
int bar;
char baz;
/** @} */
long qux;
}
https://www.stack.nl/~dimitri/doxygen/manual/grouping.html
Without the group name definition, the fields don't get properly
grouped. Instead, the group description is applied to the first field.
Fix the Intel hardware information structure, brw_device_info to
properly group the GPU hardware limitations and hardware quirks fields.
Once you've run `cd doxygen; make clean; make all`,
updated documentation can be found at

First off, st/mesa lowers DSQRT incorrectly (it uses CMP to attempt to
find out whether the input is less than 0). Secondly the current
approach (x * rsq(x)) behaves poorly for x = inf - a NaN is produced
instead of inf.
Instead we switch to the less accurate rcp(rsq(x)) method - this behaves
nicely for all valid inputs. We still don't do this for DSQRT since the
RSQ/RCP ops are *really* inaccurate, and don't even have Newton-Raphson
steps right now. Eventually we should have a separate library function
for DSQRT that does it more precisely (and perhaps move this lowering to
the post-opt phase).
This fixes a number of dEQP precision tests that were expecting better
behavior for infinite inputs.

The idea is that a single triangle will cover the whole area being
drawn, allowing the blit shader to do its work. However the max fb size
is 16384x16384, which means that the triangle we draw needs to be twice
that in order to cover the whole area fully. Increase the size of the
triangle to 32768x32768.
This fixes a number of dEQP tests that were failing because a blit was
involved which would miss some of the resulting texture.

"Braswell" is a Cherryview based *thing*. It unfortunately requires extra
information to determine its marketing name. Unlike all previous products, and
hopefully all future ones, there is no unique 1:1 mapping of PCI device ID to
brand string.
I put up a fight about adding any complexity to our GL renderer string code for
a very long time. However, a wise man made a comment to me that I couldn't argue
with: if a user installs Windows on their hardware, the brand string should be
the same as what we display in Linux. The Windows driver apparently does this
check, so we should too.
Note that I did manage to find a good use for this info anyway in the compute
shader thread counts.

The way we are organizing this code, the statically configured max_cs_threads
should always be the minimum value we actually support (ie. are aware of). As a
result, we can fall back to that if we get invalid numbers from the kernel (ie.
when the query succeeds, but the result is lower than expected).
