Fix #29259: cycles issues on certain processors. Now two versions of the kernel
are compiled, one SSE optimized and the other not, and it will choose between
them at runtime.

add support for python __doc__ comments in menu classes showing in the tooltip, since menus are used as buttons too.

One more description became easier to understand

patch [#27708] API for adding mesh properties
from Geoffrey Bantle (briggs)

Camera tracking: made some options more easy to understand

- Changed some names so now people who aren't really familiar with
motion tracking can understand what they exactly means
- Also cleaned up and rephraded some descriptions
- Changed behavior of operator which creates empty for 2d tracks:
now it operates on all selected tracks rather than active track only
- Added checkbox to enable/disable rotation stabilization

Follow-up commit to r.41765

Reviewed behaviour of selection operators, and decided that ultimately, it's
better if select left/right/column didn't change the channel selections at all.
This is because with the highlighting of the active curve nowadays, it's a bit
distracting to suddenly lose track of it after performing these operations, when
you may have been trying to select all of the keyframes on that curve for
further tweaking.

py/rna api was calling RNA_property_type more often then needed (no functional change)
