bpf: generalize is_scalar_branch_taken() logic
Generalize is_branch_taken logic for SCALAR_VALUE register to handle
cases when both registers are not constants. Previously supported
<range> vs <scalar> cases are a natural subset of more generic <range>
vs <range> set of cases.
Generalized logic relies on straightforward segment intersection checks.
