c++: contracts fixes
Fixing -Wunused-parm warnings and link errors depending on where -fcontracts
appears on the command line.
gcc/cp/ChangeLog:
* contracts.cc (build_contract_condition_function):
Set DECL_ARTIFICIAL on return value parm.
* g++spec.cc (lang_specific_driver): Add -lstdc++exp
just before -lstdc++.
