Some differences still remain due to the inability to safely fill branch delay slots and R6 compact branch forbidden slots with explicitly encoded instructions, resulting in some extra NOPs added by the assembler. - Some code duplication between toolchains which do and don't support VZ instructions is removed, since the helpers are only implemented once. When the toolchain doesn't implement the instruction an assembly macro implements it instead. - Instruction encodings are kept together in the source. On a generic kernel with KVM VZ support enabled this change saves about 2.5KiB of kernel code when TOOLCHAIN_SUPPORTS_VIRT=n, bringing it down to about 0.5KiB more than when TOOLCHAIN_SUPPORTS_VIRT=y on r6, and just 68 bytes more on r2.
