Enable xfail tests in `adjust-calling-conventions.mlir` due to LLVM Bump

[vivekkhandelwal1]

Due to the changes in upstream LLVM Project, changes have to be made to the AdjustCallingConventions pass still the pass is not fully functional as of now. Hence, some of the tests related to this pass are disabled here: #3982.

This issue is to keep track of the progress made on fixing this issue.

Hi @vivekkhandelwal1, we're hitting the same error as the disabled tests internally at Cruise. Do you have a fix ready? I'm happy to help out too! I'm aaronstgeorge on discord if you would like to chat :)
