If a member-wise assignment from a non-flattened struct to a flattened struct sees a complex R-value (not a symbol), it now creates a temporary to hold that value, to avoid repeating the R-value. This avoids, e.g, duplicating a whole function call. Also, it avoids re-using the AST node, making a new one for each member inside the member loop. The latter (re-use of AST node) was also an issue in the GetDimensions intrinsic decomposition, so this PR fixes that one too.
