Use a stricter module hash for modules as moving towards more explicit modules. Previously, a normalized target triple without deployment target is used as part of the module hash, with the assumption that deployment target should not change binary module generated.
In reality, the binary module compilation also needs to provide the typecheck for all interface to ensure the underlying C/ObjC module that built with the correct deployment target does provide the interfaces to pass typecheck. Using a stricter module hash can avoid the potentially confusing error when importing the module.
This commit adds following to module hash to distinguish swiftmodules.
