Set up benchmarking for compiler

[Roarster]

In order to benchmark the compiler we need to compare the execution time to the Apache Thrift compiler. We will do this following the documented strategy. The first phase will be to set up the benchmarking suite so it can be ran manually.

• Investigate and decide on a tool for benchmarking compiled executables
• Build a sample set of Thrift definitions to be used for benchmarking
• Decide and build a process that will allow the benchmarking to be easily ran

Once this is done, we will then be able to investigate running this as part of the build process.
