73fe848e07 Fix: Cycles log levels conflict with macros on some platforms
In particular DEBUG, but prefix all of them to be sure.

326d5bca03 Cycles: Support Decomposed MetalRT motion interpolation
Currently MetalRT interpolates transformation matrix on per-element basis
which leads to issues like #135659.

This change adds implementation of for decomposed (Scale/Rotate/Translate)
motion interpolation, matching behavior of BVH2 and other HW-RT.

This requires macOS 15 and Xcode 16 in order to use this interpolation.
On older platforms and compilers old interpolation is used.

Currently there is no changes on the user (by default) and it is only
available via CYCLES_METALRT_PCMI environment variable. This is because
there are some issues with complex motion paths that need to be looked
into. Having code available makes it easier to do further debugging.

2bf6d0fd71 Cleanup: Cycles: Remove unnecessary SSE4.2 CPU kernel
This is the minimum requirement, so just the regular kernel already
includes these instructions if supported by the CPU architecture.

30a22b92ca Cycles: Rename SSE4.1 kernel to SSE4.2
This commit updates all defines, compiler flags and cleans up some code for unused CPU capabilities.

There should be no functional change, unless it's run on a CPU that supports sse41 but not sse42. It will fallback to the SSE2 kernel in this case.

In preparation for the new SSE4.2 minimum in Blender 4.2.

bdf5649f36 Cycles: Remove redundant MetalRT workaround & add two useful DebugFlags
This patch removes a workaround for an issue that is now understood to be undefined behaviour (and fixed by #108176). It also adds two useful debug flags that we would like to be available in Blender 3.6.

654e1e901b Cycles: Use local atomics for faster shader sorting (enabled on Metal)
This patch adds two new kernels: SORT_BUCKET_PASS and SORT_WRITE_PASS. These replace PREFIX_SUM and SORTED_PATHS_ARRAY on supported devices (currently implemented on Metal, but will be trivial to enable on the other backends). The new kernels exploit sort partitioning (see D15331) by sorting each partition separately using local atomics. This can give an overall render speedup of 2-3% depending on architecture. As before, we fall back to the original non-partitioned sorting when the shader count is "too high".

a84a8a528d Cycles: remove SSE3 and AVX kernel optimization levels
While keeping SSE2, SSE4.1 and AVX2. This does not affect hardware support, it
only slightly reduces performance for some older CPUs.

To reduce maintenance cost and improve compile times.

d19e35873f Cycles: several small fixes and additions for MSL
This patch contains many small leftover fixes and additions that are
required for Metal-enablement:

- Address space fixes and a few other small compile fixes
- Addition of missing functionality to the Metal adapter headers
- Addition of various scattered `__KERNEL_METAL__` blocks (e.g. for
  atomic support & maths functions)

806521f703 Fix T92671: confusing Cycles debug logs about CPU architecture
Instead of printing debug flags listing various CPU and GPU settings that
may or may not be used, print when we are using them. This include CPU
kernel types, OptiX debugging and CUDA and HIP adaptive compilation. BVH
type was already printed.

fd25e883e2 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.
