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.
