There are some challenges to use SaveStack. Especially for multiple allocate directive statements in the same program unit. 

I am now changing my implementation to use interface defined in LLVMTranslationDialectInterface.td so that we can define our implementation in OpenMPToLLVMIRTranslation.cpp and other dialects can also use this interface and this way overhead in ModuleTranslation.cpp is also eliminated.
