This patch introduces a new options for script llvm-mca-compare.py (-plot-resource-pressure, -plot) to draw plots for llvm-mca tool statistics and option (--plot-path) to specify relative path where you want to save the plots.

The new options are used as follows:

  $ llvm-project/llvm/utils/llvm-mca-compare.py file1.s file2.s file3.s file4.s --llvm-mca-binary=build/bin/llvm-mca -plot

same as

  $ llvm-project/llvm/utils/llvm-mca-compare.py file1.s file2.s file3.s file4.s --llvm-mca-binary=build/bin/llvm-mca -plot --plot-path=./
