The Go frontend crashed doing an array assignment of two values of type
[2][]int. This patch fixes it. Normal array assignments worked because
gcc uses the same structure for all arrays with the same length and
element type. Bootstrapped and ran Go testsuite on
x86_64-unknown-linux-gnu. Committed to mainline.
