Pin frontend simulation not working for mlir binary

[Baxi]

Hello, I am trying to do cache-only simulation on an mlir-lowered binary, with llvm openmp.

Running the command

/data/dhairya/sniper/run-sniper -c rpl.cfg --frontend=pin --cache-only -- ../oracle_exe/compiled/2mm.c.mlir.out

failed on an openmp assert

On disabling KMP_AFFINITY, it apparently can't open the file /tmp/tmpz25lchn3/run_benchmarks_response.app0.th0.sift (the file doesn't exist)
