[llvm-mca] Store extra information about the driver flags used for the simulation

[markoshorro]

Summary

Added information stored in PipelineOptions and the MCSubtargetInfo.

Should this information be also printed in the "classic" report? This would require updating almost all tests.

163–174

I think that we should just ignore flags like -dispatch, -squeue, -lqueue, etc. if their value hasn't been changed by the user. I suggest to only report flags whose value doesn't correspond to their default.

The only exceptions would be mcpu/march/mtriple which (at least in my opinion) should always be present for completeness.

Ok, I agree! Do you think this information should be printed as well in the classic report?

llvm/test/tools/llvm-mca/JSON/X86/views.s

163–174

I think it should only be printed for the json output.

[markoshorro]

Added new test for output with custom parameters. Only printing parameters if values are not default.

[andreadb]

A couple of minor nits. Otherwise it LGTM.

llvm/tools/llvm-mca/PipelinePrinter.cpp

55–56

Please move this early exit before the check at line 52. We don't care about printing the register-file-size if this is an in-order processor (as we don't simulate register renaming).

Also, add an empty line after it to make the code slightly more readable.

Minor edits for readability and avoiding unnecessary information when inorder simulation
