Exchanging aFracHi / bFracHi and aFracLo / bFracLo should not affect the result of the later call to __add64. The main purpose of this commit is to prepare for "soft-fp64/fadd: Move common code out of both branches of an if-statement". v2: Fix a typo in a comment. Noticed by Matt. Results on the 308 shaders extracted from the fp64 portion of the OpenGL CTS: Tiger Lake and Ice Lake had similar results.
