Based on the robust test suite for checking property "has/in" queries, with the intention
of measuring the performance of accessing getOwnPropertyDescriptor.

Background: getOwnPropertyDescriptor and defineProperty were identified as hot code taking up
a significant chunk of startup time in a customer application. This benchmark aims to measure
the difference made by a modifying Object.getOwnPropertyDescriptor.

By current measurements, the geometric mean time of the new version is typically 1/6 that of
the current upstream implementation, using this test specifically (however, only on arm64 /
Apple M1... On Linux/x64, the results look more reasonable at a roughly 5-12% improvement in
score).

In its current form, this benchmark does very little to attempt to verify the results of the
object, which may result in branches being discarded in Turbofan (but given the enormous
difference between x64 and arm64, I'm not positive this is what is happening, and have not yet
verified this).
