[SYCL][Test] Add datalayout due to e39f6c1

e39f6c1 changed the default datalayout.
Need to add datalayout explictly to llvm/test/SYCLLowerIR/convergent.ll
to keep what we tested.

llvm/test/Transforms/SimplifyCFG/X86/switch-to-lookup-large-types.ll
delete a run line to sync to llorg version ,
1b44015 removed the line without datalayout, we somehow did a bad merge.
