RFR: 8350194: Last 2 parameters of ReturnNode::ReturnNode are swapped in the declaration

[Manuel Hässig]

The last two parameters in the declaration of ReturnNode::ReturnNode, `frameptr` and `retadr` were swapped in the declaration compared to the definition. This commit makes the declaration consistent with the definition and the two usages in [`GraphKit::gen_stub()`](https://github.com/openjdk/jdk/blob/5c552a9d64c8116161cb9ef4c777e75a2602a75b/src/hotspot/share/opto/generateOptoStub.cpp#L267) and [`Compile::return_values()`](https://github.com/openjdk/jdk/blob/5c552a9d64c8116161cb9ef4c777e75a2602a75b/src/hotspot/share/opto/parse1.cpp#L879).

Tests: tiers 1 through 3 passed.
