This reverts commit r306166 and r306168.

Revert "[ORC] Remove redundant semicolons from DEFINE_SIMPLE_CONVERSION_FUNCTIONS uses."
Revert "[ORC] Move ORC IR layer interface from addModuleSet to addModule and fix the module type as std::shared_ptr<Module>."

They broke ExecutionEngine/OrcMCJIT/test-global-ctors.ll on linux.
