LOG: [llvm-mca] Compare multiple files<br>
<br>
Script (llvm-mca-compare.py) uses llvm-mca tool to print<br>
statistics in console for multiple files.<br>
Script requires specified --llvm-mca-binary option (specified<br>
relative path to binary of llvm-mca).<br>
Options: --args [="-option1=<arg> -option2=<arg> ..."], -v or -h can also be used.<br>
<br>
The script is used as follows:<br>
$ llvm-project/llvm/utils/llvm-mca-compare.py file1.s --llvm-mca-binary=build/bin/llvm-mca<br>
