Currently the llvm-mca supports getting the benchmark of a single file only. This patch introduces an option to compare multiple .S files.

The new option (-diff) is used as follows:

$ llvm-mca example1.s example2.s -diff
$ llvm-mca example1.s example2.s -diff -json
$ llvm-mca example1.s example2.s example3.s example4.s -diff

We've found it usefull internally when comparing results of multiple builds, by using some pretty printers written in python, that can be found at https://github.com/mmatic05/llvm-project/tree/LLVM-MCA#applying-the-script-to-assembly-code-obtained-from-llvmtoolsllcllccpp.
