Wang, Pengfei c22dc71b12 [CodeGen][X86] Remove unused trivial check-prefixes from all CodeGen/X86 directory. 
I had manually removed unused prefixes from CodeGen/X86 directory for more than 100 tests.
I checked the change history for each of them at the beginning, and then I mainly focused on the format since I found all of the unused prefixes were result from either insensible copy or residuum after functional update.
I think it's OK to remove the remaining X86 tests by script now. I wrote a rough script which works for me in most tests. I put it in llvm/utils temporarily for review and hope it may help other components owners.
The tests in this patch are all generated by the tool and checked by update tool for the autogenerated tests. I skimmed them and checked about 30 tests and didn't find any unexpected changes.

; On x86, an atomic rmw operation that does not modify the value in memory
; (such as atomic add 0) can be replaced by an mfence followed by a mov.
