(grokvardecl): Don't call mangle_decl.
* except.c (nothrow_libfn_p): Look at DECL_NAME, not
DECL_ASSEMBLER_NAME.
* method.c (set_mangled_name_for_decl): Delete.
* name-lookup.c (pushdecl): When a local extern shadows a
file-scope declaration of the same object, give both DECLs the
same DECL_UID.
* typeck.c (cxx_mark_addressable): Don't set TREE_ADDRESSABLE
on DECL_ASSEMBLER_NAME.

builtins.c (fold_builtin_unordered_cmp): Take an EXP argument instead of both an ARGLIST and a result TYPE.
* builtins.c (fold_builtin_unordered_cmp): Take an EXP argument
instead of both an ARGLIST and a result TYPE. Handle these C99
comparison functions as "polymorphic" builtins. Also handle
lowering of BUILT_IN_ISUNORDERED to an UNORDERED_EXPR tree node.
(fold_builtin_1): Update calls to fold_builtin_unordered_cmp.
Move handling of BUILT_IN_ISUNORDERED from here to there.
