Example source where `mmu` variable metadata gets stripped after applying
globalopt
When using the globalopt optimization (every optimization level except O0) the
debug metadata is partially removed, and there is no more reference to the
global value inside the associated variable metadata. This interferes with any
subsequent passes that might make use of such debug info.</pre>
