through the use of 'fpmath' metadata. Currently this only provides a 'fpaccuracy' value, which may be a number in ULPs or the keyword 'fast', however the intent is that this will be extended with additional information about NaN's, infinities etc later. No optimizations have been hooked up to this so far. llvm-svn: 154822
