Hash :902bfdca Message :Mop up RC4_INDEX.
The RC4_INDEX define switches between base pointer indexing and per-byte
pointer increment. This supposedly made a huge difference to performance
on x86 at some point, however compilers have improved somewhat since then.
There is no change (or effectively no change) in generated assembly on
a the majority of LLVM platforms and even when there is some change
(e.g. aarch64), there is no noticable performance difference.
Simplify the (still messy) macros/code and mop up RC4_INDEX.
