Math.hypot with 3 arguments fails ES6 math tests on linux/armv7
https://bugs.webkit.org/show_bug.cgi?id=291074
Reviewed by Yusuke Suzuki.
While Math.hypot(Math.hypot(a, b), c) is mathematically the same as
Math.hypot(a, b, c), in practice the calculation in libstdc++ ends up
slightly off. Use the 3-argument version instead.
AFAICT the libstdc++ implementation does not have the JS-expected
behavior with regard to NaNs, so explicitly check for that.
