2021 (pushlevel): Ignore argument. Do not push another binding
2022 level on the transition from the parameters to the top level
2023 of the function body; just tweak the flags and proceed.

2075 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
2076 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
2077 (duplicate-decls): For real parm decl after a forward decl,
2078 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
