Pin maximum functor arity to 10

The compiler needs an arity of 10 to compile itself into Java.
Gerrit Code Review pins the arity to 8 to ensure an optimized
code path is always used.

Simplify the virtual machine code by pinning the arity to 10 and
extending the choice point saving optimization for all ranges.
This eliminates some weird code paths using an array for extra
registers beyond the optimized 8.

Simplify register naming by using r1...r10 instead of areg1...areg10.
