Shows new, reference and diff renders, with mouse hover to flip between
new and ref for easy comparison. This generates a report.html in
build_dir/tests/cycles, stored along with the new and diff images.

* Remove some unnecessary SSE emulation defines.
* Use full precision float division so we can enable it.
* Add sqrt(), sqr(), fabs(), shuffle variations, mask().
* Optimize reduce_add(), select().

I need to use some macros defined in util_simd.h for float3/float4, to emulate
SSE4 instructions on SSE2. But due to issues with order of header includes this
was not possible, this does some refactoring to make it work.

We already detect this automatically based on shading nodes and per shader
settings, and performance of this option is ok now all devices.

Two main things here:
1. Replace all unsafe for #line directive characters into a single loop,
avoiding multiple iterations and multiple temporary strings created.
2. Don't merge token char by char but calculate start and end point and
then copy all substring at once.
This gives about 15% speedup of source processing time. At this point
(with all previous commits from today) we've shrinked down compiled
sources size from 108 MB down to ~5.5 MB and lowered processing time
from 4.5 sec down to 0.047 sec on my laptop running Linux (this was a
constant time which Blender will always spent first time loading kernel,
even if we've got compiled clbin).
Add a safe version of normalize since all uses of normalize
did zero length checks, move this into a function.
Also avoid unnecessary conversion.
Gives minor speedup here (approx 3-5%).
Basically gather lines as-is during traversal, avoiding allocating
memory for all the lines in headers.
Brings additional performance improvement abut 20%.
The idea here is that it is possible to mark certain include statements
as "precompiled" which means all subsequent includes of that file will
be replaced with an empty string.
This is a way to deal with tricky include pattern happening in single
program OpenCL split kernel which was including bunch of headers about
10 times.
This brings preprocessing time from ~1sec to ~0.1sec on my laptop.
The idea is to re-use files which were already processed. Gives about 4x speedup
of processing time (~4.5sec vs 1.0sec) on my laptop for the whole OpenCL kernel.
For users it will mean lower delay before OpenCL rendering might start.
This is still far from prefect, but yet much better than what we had so
far (more consistent with inheritent precision available in floats).
Note that this fixes some (currently commented out) units unittests, and
requires adjusting some others, will be done in next commit.
Bug was in RNA nodes code actually, itemf functions shall never, ever
return NULL!
Note that there were other itemf functions there that were potentially
buggy. Also harmonized a bit their code.
* Numbers with units (especially, angles) where not handled correctly
regarding number of significant digits (spotted by @brecht in T52222
comment, thanks).
* Zero value has no valid log, need to take that into account!
When calling sculpt from Python,
setting 3D 'location' but not 2D 'mouse' stopped working in 2.78.
Now check if the operator is running non-interactively and
skip the mouse-over check.
Regression in D1812: PyDriver variables as Objects
Taking the Python representation is nice in general
but for enums it would convert them into strings,
breaking some existing drivers.
Some users really liked previous behavior,
so making it an option.
Cursor Lock Adjustment can be disabled to give something close to
2.4x behavior of cursor locking.
When lock-adjustment is disabled placing the cursor the view.
This avoids the issue reported in T40353
where the cursor could get *lost*.
Even strands that were excluded by the density texture were being added
to the DM passed to cloth, but these ended up having some invalid data,
because they were not fully constructed.
This simply excludes `UNEXISTED` particles from the DM generation, as
would be expected.
Note that fix is not perfect, systematically make refcounting of all IDs
assigned to node's id pointer, which breaks the 'do not refcount
scene/object/text datablocks' principle...
But besides that principle being far from ideal in general, it becomes
pretty much impossible to apply when using //generic// ID pointer,
unless we add some kind of type data to that pointer somehow.
So for now, better to live with that, than having broken usercount.
