Thanks to jsji for making me realize that a lot of the functionality I implemented in this patch already existed.  I converted the ExpandFloatRes/Op_STRICT_* functions to use ExpandChainLibCall and eliminated the LibCallifyStrictFP and MakeLibCallChained functions from the previous diffs.

I also added a test that ensures that the serial properties of strictFP functions are maintained.
