Fix truncating of doubles to integers

When analyzing the data flow and determining that a double is or'ed with
0, we correctly assume a cast to an integer and insert a convert
instruction in the IR instead of the actual bitwise or.. The JIT
implements that, but the interpreter doesn't, resulting in incorrect
values.

This problem is specific to the SSA optimizer and the underlying isel
requirements in 5.9 and does not apply to the design of the code
generator in 5.11 and onwards.
