* Added a benchmark for KeyPaths where trivially-typed memory is preceded by non-trivially-typed memory.
* Reduces the workload of run_KeyPathClassStructs by a factor of 4.
The reported time was 1847 us.
* Add benchmarks that measure KeyPath read and write performance.
* Added setUpFunctions. Revised number of iterations per benchmark.
* Include n as a factor in the number of iterations.
* Increased number of iterations for KeyPathDirectAccess by a factor of 25.
* One last tweak to the number of iterations on testDirectAccess to get them above 20 us.
* Made revisions based on feedback. Added three new benchmarks.
* Added benchmarks to exhaustively benchmark all KeyPathComponent types. Removed benchmarks dealing with an inlining issue.
* Wrapped additional keypaths with identity() where needed. More cleanup and documentation.
* Moved KeyPaths for KeyPathRead and Write into FixedSizeArrayHolder. Renamed GetSet to Getset.
* Added inline(never) to both versions of getKeypathToElement().
* Moved identity() wraps so that they're called once per variable per benchmark.
* Moving destinationKeyPaths into FixedSizeArrayHolder to try to reduce long setup overhead errors.
* Additional moving of the identity() wrapping into the singleton's init() to try to reduce setup time errors.
