5d51a788f7 - revert r47208 
* properly fix the internalerror it hid: only replace the local symbols
    migrated to the parentfpstruct right before generating debug information,
    so that internally generated self/result loads during optimisation passes
    don't get confused by the replacement absolutevarsyms (those are normally
    never encountered during optimisation, as regular absolutevarsyms are
    replaced during parsing)
