While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

In the Auto Merge & Split feature, multithreading was only used to
find duplicates between vertex and another vertex.
But with this patch, multithreading is now used to find intersections
etween edge and edge and between edge and vertex.
In my tests I noticed a performance improvement of around 180%
(0.017151 secs to 0.009373 secs)

Previously, compared to `Auto Merge` without `Split Edges & Faces`,
`Auto Merge` with this option ignored duplicates between selected
vertices. It only considered duplicates between selected vertices and
unselected vertices.
This is a regress and not a progress.
This commit implements this behavior, so this option matches the other
`Auto Merge`.
