[trunk][patch] Avoid sharing DECL_ARGUMENTS

[Rafael Espindola]

Normally a function argument points back to the function DECL via
DECL_CONTEXT. If two FUNCTION_DECLs share DECL_ARGUMENTS, the
DECL_CONTEXT of the arguments must be incorrect for at least one of
the functions.

This patch fixes one case where this was happening.

        * c-decl.c (merge_decls): Make sure newdecl and olddecl don't
        share the argument list.

Cheers,
