There is a chance parts of Blender call BKE_object_workob_calc_parent
with ob->parent objects that are outside the depsgraph.
This we can tackle later since these are corner cases anyways,
and this fix fixes all parenting operators in Blender.
This commit contains the minimum to make clang build/work with blender, asan and ninja build support is forthcoming
Things to note:
1) Builds and runs, and is able to pass all tests (except for the freestyle_stroke_material.blend test which was broken at that time for all platforms by the looks of it)
2) It's slightly faster than msvc when using cycles. (time in seconds, on an i7-3370)

3) clang on windows uses a drop in replacement for the Microsoft cl.exe (takes some of the Microsoft parameters, but not all, and takes some of the clang parameters but not all) and uses ms headers + libraries + linker, so you still need visual studio installed and will use our existing vc14 svn libs.
4) X64 only currently, X86 builds but crashes on startup.
5) Tested with llvm/clang 6.0.0
6) Requires visual studio integration, available at https://github.com/LazyDodo/llvm-vs2017-integration
7) The Microsoft compiler spawns a few copies of cl in parallel to get faster build times, clang doesn't, so the build time is 3-4x slower than with msvc.
8) No openmp support yet. Have not looked at this much, the binary distribution of clang doesn't seem to include it on windows.
9) No ASAN support yet, some of the sanitizers can be made to work, but it was decided to leave support out of this commit.

This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources.
The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp.
Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried.
Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file.
The user interface of the node is similar to the script node, the user can either select an internal Text or load a file.
Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot.
The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light,
rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.

The problem was that the particle system modifier was reading ob->derivedDeform
during modifier stack evaluation. Due to the mesh -> DM conversion this was no
longer set leading to wrong results.
In fact we don't really need the deformed mesh, just the original mesh topology
for face/poly index remapping. So the solution is to use that instead.
This commit adds number formatting (thousands separator) to the baking panel. It also adds a new function to format memory sizes (KB/GB/etc) and applies it to the baking panel and scene stats. The new function is unit tested.

* Added BKE_object_get_evaluated_mesh, which can also be used outside of
Modifier context.
* BKE_modifier_get_evaluated_mesh_from_object is now a dummy wrapper
around BKE_object_get_evaluated_mesh, we do not need anything special
anymore for RENDER quality option, since this is supposed to be handled
at depsgraph level... Maybe we can get rid of it at some point, but kind
of like the idea of keeping it for now, sounds more consitent.
* Always use BKE_id_new, unless you have a very good reason to use
lower-level code!
* Prefer to pass actual ID user pointer to functions like id_us_plus & co,
rather than 'floating' ID pointer, when possible. It makes it more clear
who is the user we increase count for!
Don't store pointers to ViewLayer in the workspace, only names. Add specific
relation type since the generic mechanism makes the code hard to follow.
Integrate with pointer restore for undo and library remapping code to avoid
data going out of sync.
Also add relation automatically if there doesn't exists one yet in
BKE_workspace_view_layer_get, because in general it's really hard to ensure
it will exist when making arbitrary scene changes.

This fix applying the following modifiers:
* Boolean (working already)
* Array
* Mesh Deform
* Surface Deform
* Vertex Weight Proximity
This function was to return evaluated mesh. So it should get the evaluated
object at all times. So in this case it makes more sense to simply pass the
depsgraph (or in this case the ModifierEvalContext that contains both the
depsgraph and the flag.
Solution discussed with Bastien Montagne.
The modifier is still quite slow; this could be due to caches being written
to a CoW datablock instead of the original one. More investigation is
needed.
Allows more than one snap mode to be enabled. So different combinations are possible.
