The format is currently inconsistent. Use the https://llvm.org/docs/CodingStandards.html#error-and-warning-messages style.

And add `error:` or `warning:` to CHECK lines wherever appropriate.

Matthew Voss 6da7d31416 [llvm-profdata] Emit Error when Invalid MemOpSize Section is Created by llvm-profdata 
Under certain (currently unknown) conditions, llvm-profdata is outputting
profiles that have two consecutive entries in the MemOPSize section for the
value 0. This causes the PGOMemOPSizeOpt pass to output an invalid switch
instruction with two cases for 0. As mentioned, we’re not quite sure what’s
causing this to happen, but this patch prevents llvm-profdata from outputting a
profile that has this problem and gives an error with a request for a
reproducible.
