Shu-Chun Weng df64d52310 More aggressively prevent a buffer from being optimized out
The volatile global variable was first introduced in e86f9654c. I have
noticed the compiler still optimizing the buffer out on AArch64
presumably because the assignment is after all other observable
behaviors so it's still valid to eliminate it.
