Yaxun Liu d0585d352f [InferAddressSpaces] Fix assertion about null pointer 
InferAddressSpaces does not check address space in collectFlatAddressExpressions,
which causes values with non flat address space put into Postorder and causes
assertion in cloneValueWithNewAddressSpace.

This patch fixes assertion in OpenCL 2.0 conformance test generic_address_space
subtest for amdgcn target.
