+/// An `omp.target` `in_reduction` operand is captured by a `map_entries` entry
+/// when the entry's `MapInfoOp` var_ptr is the same SSA value, or another
+/// result of the same defining op (block arguments, which have no defining op,
+/// match only by exact identity). Flang emits `hlfir.declare`#0 for the
+/// `in_reduction` operand and `hlfir.declare`#1 for the map var_ptr. Keep this
+/// predicate in sync with `targetInReductionCapturedBy` in
+/// OpenMPToLLVMIRTranslation.cpp so translation matches what the verifier
+/// accepts.
