[PassTimingInfo] Stop double (or worse) counting passes/analyses
If we nest timers, we end up double counting anything nested.
The most egregious is ModuleInlinerWrapperPass/DevirtSCCRepeatedPass showing up as >20% of the total time when they're just wrappers.
Analyses also end up getting counted multiple times because they're nested inside wrappers and passes.
Ignore ModuleInlinerWrapperPass/DevirtSCCRepeatedPass and put analyses into their own TimerGroup.
