>> Description: The current name MemNode::memory_type() is misleading because the returned type is a property of the value that is loaded/stored, not the memory that is accessed. Usually, the two of them match, but for mismatched memory accesses (arising e.g. from using Unsafe or memory segments) they might differ, e.g. one might store a value of type 'short' into an array of elements of type 'long'. The proposal was to rename MemNode::memory_type() to MemNode::value_basic_type() to clarify these cases.
