Description
This is especially useful in the context of Windows where overcommit is impossible (i.e. it would in most cases show possible regressions in Windows even if tests are run on Linux). Ideal program would have max-rss and max-vmem close to each other.

Research direction
Start by tracing where rustc-perf currently records max-rss and how benchmark results are collected on Windows and Linux. Determine how to measure maximum virtual memory and compare max-vmem with max-rss; done means the metric is collected consistently and exposes regressions on Windows without relying on Linux overcommit.
