<summary>Changes</summary>

This change does two kinds of splits:
- Splits each target into a different file. Some targets are left in the same files, such as riscv32/64 and x86/_64 as these tests and lists are very similar.
- Splits up the very long 'note:' lines which contain a list of CPUs, using `CHECK-SAME`. There was a note about this not being possible before, but with `--implicit-check-not`, this is now possible -- I have verified that this does the right thing if a single CPU anywhere in the list is left out.

These tests had become quite annoying to change when adding a CPU, and I believe this change makes these easier to maintain, and should cut down on conflicts in these files (or at least makes conflicts easier to resolve).

I apologise in advance for downstream conflicts, but hopefully that's a small amount of short term pain, in return for fewer conflicts in future.
