bpf: Allow instructions with arena source and non-arena dest registers
The compiler sometimes stores the result of a PTR_TO_ARENA and SCALAR
operation into the scalar register rather than the pointer register.
Relax the verifier to allow operations between a source arena register
and a destination non-arena register, marking the destination's value
as a PTR_TO_ARENA.
