Optimization passes for the generated LLVM code.

Merge branch 'master' into asset-engine

Merge branch 'master' into id-remap

Completed basic expression tree code generation.

The code uses a pointer-based signature convention for node functions,
which helps to avoid issues with type coercion through clang.
In the future we could either find a more reliable way to produce llvm IR
for the nodes, or use node functions as external functions without inlining.

Cleanup: remove unneeded 3d cursor position changes.

Polish import/export UI a bit.

fix for solver / cluster solver iterations override, it caused different behavior at loading / refresh

solver iteration override was taken into account too late, after first validation which probably caused different simulation behavior using the default value for one frame

Merge branch 'master' into alembic_basic_io

Use annotation attributes on module functions to avoid name mangling issues.

Names in C++ code tend to get mangled by the clang compiler according to the
respective target ABI. This is unfortunate because it makes it difficult to
map functions to nodes by name. For now we use a function attribute in the module
C++ code to pass on the "true" name of the function and map them internally.

Make LLVM module compilation depend on header files to force recompile when headers change.

Always reset to default asset engine (i.e. regular filebrowser code) when opening a new browser.

Else we'd have the last used engine even when saving a .blend or picture, ugly!
