(2 ^ 62) - 1 returns -1 on LLVM back-end

[cgay]

format-out("%d", (2 ^ 61) - 1) gets an overflow error, as expected.

$ _build/bin/hello
Integer overflow: The result of the last operation is too large for this integer representation.

format-out("%d", (2 ^ 62) - 1) prints -1.

$ _build/bin/hello
-1

Fixed in PR#1256.

There is a compiler error when using the C back end, which I think was introduced by the regression test for this bug.
