7a0575b9a8 InstCombine: fix a bug when combining (fcmp cc0 x, y) && (fcmp cc1 x, y).
uno && ueq was converted to ueq, it should be converted to uno.

matter.

3e054fe9ef Use opt -S instead of piping bitcode output through llvm-dis.

b1e1e82c54 Change these tests to feed the assembly files to opt directly, instead
of using llvm-as, now that opt supports this.

4990b257dd - Somehow I forgot about one / une.
- Renumber fcmp predicates to match their icmp counterparts.
- Try swapping operands to expose more optimization opportunities.

8db90725cb Optimize anding of two fcmp into a single fcmp if the operands are the same. e.g. uno && ueq -> ueq
ord && olt -> olt
     ord && ueq -> oeq
