Detailed Description
A wrapper pass for external alias analyses.
This just squirrels away the callback used to run any analyses and register their results.

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.
If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.
Reimplemented from llvm::Pass.

◆ RunEarly
| bool llvm::ExternalAAWrapperPass::RunEarly = false |
Flag indicating whether this external AA should run before Basic AA.
This flag is for LegacyPassManager only. To run an external AA early with the NewPassManager, override the registerEarlyDefaultAliasAnalyses method on the target machine.
By default, external AA passes are run after Basic AA. If this flag is set to true, the external AA will be run before Basic AA during alias analysis.
For some targets, we prefer to run the external AA early to improve compile time as it has more target-specific information. This is particularly useful when the external AA can provide more precise results than Basic AA so that Basic AA does not need to spend time recomputing them.
