ir.StaticValue currently relies on CaptureVars setting Addrtaken for variables that are assigned within nested function literals. We want to move that logic to escape analysis, but ir.StaticValue is used in inlining and devirtualization, which happen before escape analysis. The long-term solution here is to generalize escape analysis's precise reassignment tracking for use by other optimization passes, but for now we just generalize ir.StaticValue to not depend on Addrtaken anymore. Instead, it now also pays attention to OADDR nodes as well as recurses into OCLOSURE bodies. Passes toolstash -cmp.
