Benchmarking The Intel Performance Change With Linux FSGSBASE Support

There wasn't much change with PostgreSQL.

The Apache performance was running better with this latest code.

So there are some improvements to note at this time with the wip.x86/cpu branch containing the FSGSBASE enablement. However, at least for this Core i9 7980XE system still wasn't anywhere close to meeting the mitigation costs incurred by Spectre/Meltdown/L1TF/Zombieload. Nevertheless, any and all performance improvements for the Linux kernel are certainly welcome and we look forward to more testing with Linux 5.3.
