We should patch queue the bump of the toolchain on the performance project to ensure that the new compiler is not worse than the old.

Two perf runs:

https://evergreen.mongodb.com/version/571e5d3f3ff1222e2c000a57_0

There are mixed results. We see improvements to YCSB runs, but an 8.5% drop in YCSB loads. From my local Linux (12 core) to Windows 10 (12 core), I do not see a negligible change when running the jtrue.js workload.
