GlobalsModRef, ValueTracking: Look through threadlocal.address intrinsic (#88418)
This improves handling of `threadlocal.address` intrinsic in analyses: The thread-id cannot change within a function with the exception of suspend points of pre-split coroutines. This changes `llvm::getUnderlyingObject` to look through `threadlocal.address` in these cases. `GlobalsAAResult::AnalyzeUsesOfPointer` checks whether an address can be traced to simple loads/stores or escapes to other places. Starting the analysis from a thread-local `GlobalValue` the `threadlocal.address` intrinsic is safe to skip here. This improves issue #87437
