Subject: [PATCH] [LLVM] Fix missing includes for function declarations that
 will be needed for explicit symbol visibility (#103900)

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
