This Serializer which is implemented
external to the IR node definition
uses a StringBuilder to achieve about a
1.7x performance improvement when serializing.
Eventually, all implementations of the
`serialize` methd should be replaced with
a call to `Serializer.serialize`.
However, for this PR we keep the old
code in place in order to allow for easy
regression testing with the benchmark JAR
like this:
> java -cp utils/bin/firrtl-benchmark.jar \
firrtl.benchmark.hot.SerializationBenchmark \
~/benchmarks/medium.pb 2 5 test

* 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.
