trans: Optimize initialization using repeat expressions
This elides initialization for zero-sized arrays: * for zero-sized elements we previously emitted an empty loop * for arrays with a length of zero we previously emitted a loop with zero iterations This emits llvm.memset() instead of a loop over each element when: * all elements are zero integers * elements are byte sized
