[X86] Rename O3-pipeline.ll to opt-pipeline.ll and add O1/O2 command lines

Eric Cristopher asked me about possibly disabling some passes at
-O1/Og. Figured a good first step was to test all the pipelines.
They all appear to be the same for now. Hoping we can use FileCheck
prefixes for differences to avoid repeating the contents 3 times.
