[PATCH] XCore fix for SingleSource/Benchmarks/Misc-C++/Large/sphereflake

[Renato Golin]

  Hi Robert,

  I tested this on AArch64 (where it's also failing, probably for similar reasons since the image looks identical), and it still fails on both GCC and Clang, each generating a slightly different output.

  I know it's ugly, but rounding it shorter might be the overall best solution. It's not unprecedented.

  cheers,
