replace spinlock by QemuMutex.
spinlock is only used in two cases: * cpu-exec.c: to protect TranslationBlock * mem_helper.c: for lock helper in target-i386 (which seems broken). It's a pthread_mutex_t in user-mode, so we can use QemuMutex directly, with an #ifdef. The #ifdef will be removed when multithreaded TCG will need the mutex as well.
