Cycles: use SPDX license headers * Replace license text in headers with SPDX identifiers. * Remove specific license info from outdated readme.txt, instead leave details to the source files. * Add list of SPDX license identifiers used, and corresponding license texts. * Update copyright dates while we're at it.

Cycles Refactor: Add SSE Utility code from Embree for cleaner SSE code. This makes the code a bit easier to understand, and might come in handy if we want to reuse more Embree code. Differential Revision: https://developer.blender.org/D482 Code by Brecht, with fixes by Lockal, Sergey and myself.

Cycles: Add an option to build single kernel only which fits current CPU This seems quite useful for the development, so you don't need to wait all the kernels to be re-compiled when working on a new feature, which speeds up re-iteration. Marked as an advanced option, so if it doesn't work so well in practice it's safe to revert anyway.

Cycles: Fix compilation error on 32bit platforms

Cycles: Slight modification to the previous commit This way util_simd.cpp would not require modifications if/when SSE2 is suddenly supported on 32bit platforms. This also allowed to unleash some issues with util_simd.h related on the fact that there size_t and int are actually the same types.

# define __KERNEL_SSE2__
Cycles: remove prefix from source code file names Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.
