In multiple source files function definitions never sees there declaration in a header because its never included causing linker errors when explicit symbol visibility macros\dllexport are added to the declarations.

Most of these were originally found by @<!-- -->tstellar in https://github.com/llvm/llvm-project/pull/67502

TargetRegistry.h is needed in MCExternalSymbolizer.cpp for createMCSymbolizer 
Analysis/Passes.h is needed in LazyValueInfo.cpp and RegionInfo.cpp for createLazyValueInfoPassin and createRegionInfoPass 
Transforms/Scalar.h is needed in SpeculativeExecution.cpp for createSpeculativeExecutionPass
