Mircea Trofin e90406ee2a [llvm] Make new pass manager's OptimizationLevel a class ... Summary: The old pass manager separated speed optimization and size optimization levels into two unsigned values. Coallescing both in an enum in the new pass manager may lead to unintentional casts and comparisons. In particular, taking a look at how the loop unroll passes were constructed previously, the Os/Oz are now (==new pass manager) treated just like O3, likely unintentionally. This change disallows raw comparisons between optimization levels, to avoid such unintended effects. As an effect, the O{s|z} behavior changes for loop unrolling and loop unroll and jam, matching O2 rather than O3. The change also parameterizes the threshold values used for loop unrolling, primarily to aid testing.
