This commit resolves an ICE in cp_tree_equal when comparing REFLECT_BASE nodes, which arose from a recent change in reflection handling. When comparing REFLECT_BASE nodes with different TREE_CODE values the compiler would previously crash. This commit fixes this issue by directly comparing the pointers of the REFLECT_BASE nodes, preventing the erroneous call to cp_tree_equal with unexpected input and thus the ICE. A new test case is added to prevent regressions.
