If the symbol node is interpolated like this `:"#{foo}"` the instruction sequence should be `putstring` followed by `intern`. In this case it was a `putobject` causing the `test_yjit` tests to fail. Note that yjit is not required to reproduce - the instructions are `putstring` and `intern` for yjit and non-yjit with the original parser. To fix I moved `pm_interpolated_node_compile` out of the else, and entirely removed the conditional. `pm_interpolated_node_compile` knows how / when to use `putstring` over `putobject` already. The `intern` is then added by removing the conditional. Before: ``` == disasm: #<ISeq:<main>@test2.rb:1 (1,0)-(1,11)> 0000 putobject :foo ( 1)[Li] 0002 leave ``` After: ``` == disasm: #<ISeq:<main>@test2.rb:1 (1,0)-(1,11)> 0000 putstring "foo" ( 1)[Li] 0002 intern 0003 leave ``` Fixes the test `TestYJIT#test_compile_dynamic_symbol`.
