Arthur Eubanks 0cd27cdc3a [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.
