[opt][timers] Fix time-passes.ll test failing on reversed iterators (llvm#131941)

After llvm#131217 was submitted,
time-passes.ll fails because `opt` prints `-time-report` when
`ManagedTimerGlobals` is destroyed. `ManagedTimerGlobals` stores
`TimerGroup`s in an unordered map, so the ordering of the output
`TimerGroup`s depends on the underlying iterator.

To fix this, we do what Clang does and use
`llvm::TimerGroup::printAll(...)`, which *is* deterministic. This is
also what Clang does. This does put move analysis section before the
pass section for `-time-report`, but again, this is also what Clang
currently does.
