1820 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1821 current_binding_level->tags if asked for thislevel_only or if
1822 we might have to diagnose "struct foo; union foo;"
1823 (pushlevel): Ignore argument. Do not push another binding
1824 level on the transition from the parameters to the top level
1825 of the function body; just tweak the flags and proceed.
1826 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1827 a function body, separate the parameter list from the
1828 top-level local variables.

1876 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1877 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1878 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1879 (duplicate-decls): For real parm decl after a forward decl,
1880 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1881 foo(...) { } with only a warning. Say whether a previous
1882 declaration was implicit.
1883 (warn_if_shadowing): Now handles all shadowing, not just
1884 local-over-local. Clarify comments.
1885 (pushdecl): Rewritten. There is no longer a distinction
1886 between global and local symbol values; they're all
1887 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1888 DECL_EXTERNAL decls, and use any_external_decl to check
