arm: Fix maybe-uninitialized GCC warnings
GCC 7 generates maybe-uninitialized warnings at the code that updates the "dest" variables in the writeVecElem function of neon64_mem.hh file. It is because the generated code does not appropriately initialize the output variable before passing it to the writeVecElem function. This patch initializes the output variable to fix this.
