Workaround 'unused variable' cppcheck style warnings

* include/private/gc_locks.h [PCR && THREADS] (DCL_LOCK_STATE): Define
to empty if CPPCHECK.
* mach_dep.c [MACOS && __MWERKS__ && POWERPC] (getRegisters): Declare
as external of CPPCHECK (as cppcheck does not recognize "asm" in
function declaration).
