Do not use bitwise OR on bool

[akuzm]

This has unexpected semantics and can prevent optimizations. Note that the current code still returns the correct results, so this is mostly a cosmetic change.

Can we have test to confirm correct semantics

Can we have test to confirm correct semantics

This is tested heavily by vector_agg_functions. The results were actually correct, but I think it is error-prone and might prevent some optimizations, so I changed it to use boolean operations. A cosmetic change, basically.
