Example of input:
`abs D2, D19  // ABS <V><d>, <V><n>  \\ ASIMD arith, basic  \\ 1 2  2  4.0 V1UnitV`
1: micro ops, 2: latency, 2: bypass latency, 4.0: throughput (not reverse), Units with release at cycle if needed.
Output:
` 1  2  0.25  2  V1UnitV   ABSv1i64   abs  d2, d19 // ABS <V><d>, <V><n>  \\ ASIMD arith, basic  \\ 1 2  2  4.0 V1UnitV`

I can then use a script to check automatically values in comments compared to values returned by llvm-mca.
