The Lit in subject fails on z/OS since the input file `Inputs/split-layout.profdata` is marked as ASCII even though it is binary and the output file `Output/sample-split-layout.test.tmp-output` is binary. 

This PR removes the diff command which fails because it compares a binary file and a text file. The rational is that this diff command seems to be redundant to the `FileCheck` on the next command.
