Summary: This patch moves the test cases related to Attributor to `Transforms/Attributor` folder. We have used `Transforms/FunctionAttrs` as the primary folder for Attributor test but we need to change testing way now. For the test cases which I think functionattrs doesn't infer anything something like (willreturn, nosync, value-simplify, h2s ..etc), I moved them with the command `git mv`. For the test cases in which functoinattrs and attributor are tested, I copied the test to the folder and remove the check only used by functoinattrs.
