testcase

Related to bug 120033, another failure on the emscripten test suite, on a 64-bit math testcase. Output differs from v8 and sm, e.g. in jsc the last line is

signed 63: 0,4700334401769964867,4700334401769964867,-4700334401769964867,0,0,0,0,0

but should be

signed 63: 2635267980966005246,7574178278953946467,-8237297813789599903,-4938910297987941221,1110862422097806138,0,2,2635267980966005246,2303642317021935975

This works, I assume fixed by the fix to bug 120033.
