Batch renames in LowerTypes (#1718)
* Batch renames in LowerTypes
Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
* Add benchmarking for LowerTypes
Add infrastructure of benchmarking Transforms (in addition to
existing infra for Passes). Also run System.gc between each timed
benchmark to improve stability.
