The performance impact of different parts of this patch can be seen here: https://llvm-compile-time-tracker.com/index.php?branch=dobbelaj-snps/perf/test_instructions_20200907-01

- Introducing the 'NumUserOperandsDelta' has a measurable impact on the number of instructions as it affects every instruction. Maybe that can be avoided ?
- Introducing the optional extra argument for LoadInst/StoreInst has (as expected) some effect on the RSS.
