IMPALA-11459: Use new LLVM Pass Manager
LLVM developed a new pass manager -
https://llvm.org/docs/NewPassManager.html - to overcome some of the
limitations of LegacyPassManager. It offers improved optimization
performance by reusing analysis across all types and levels of
optimization passes. It also appears to be better maintained in future
releases of LLVM.
Switches to using the new PassManager via PassBuilder and a
ModulePassManager. Breaks out PruneModule into a separate
FunctionPruneTime timer to more easily track any regressions there.
