For archeologists (I should actually have included this into my commit
message, but alas), this creates an `ORE` object on demand rather than
using the analysis as OptRemarkAnalysis is a function pass while
PGOInstrumentation is a ModulePass.
Pretty much every other ModulePass using ORE needs to follow the same
pattern (see e.g. the PartialInliner).
