2867c85a37 Remove support for the special 'fast' value for fpmath accuracy for the moment.

8883c43ddc Make it possible to indicate relaxed floating point requirements at the IR level
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.
