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

[robert lytton]

  Hi Tim, Renato, Daniel,

  Thanks for the input.

  The trouble with rounding is deciding a rules for rounding that everyone agrees with.
  You have to draw an arbitrary line and two libraries could still end up on either side.

  I think having the LLVM_sin() not call an underlying library is the only solution.
  Are you happy if I pick a suitable C implementation to use instead?
  How about: http://lab.polygonal.de/?p=205
  Would a low precision be OK?

  Robert
