Supporting de-virtualization for precise types.
Sharpening invoke-virtual and invoke-interface calls to invoke-direct for cases
where the type of "this" pointer in the invoke- params is precisely known.
Instructions that have an invoke opcode are marked as interesting, for each invoke-virtual/interface
we come across with a precise type for "this" we mark the location as a candidate for sharpening,
resolve the concrete method and save its method reference <DexFile, DexMethodIndex> to be sharpened
in CompilerDriver::ComputeInvokeInfo().
Added a new entry to AOT statistics showing the percentage of sharpened calls that were based on
type analysis.
Fix a minor bug in type creation for GetSuperClass(). Previously super class of a precise reference
had precise types created which is not necessarily the case.
Fixed DCHECK in Class::FindVirtualMethodForVirtual to handle cases for Miranda methods.
