[PATCH] D39304: [IR] redefine 'reassoc' fast-math-flag and add 'trans' fast-math-flag

As a vendor llvm for Apple targets has actually run into the incompatibility issue with old fast and current fast, we elected to use version markers in the IR for in house code to tell us that the old fast is relevant in the bit code reader during auto upgrade for IR.
