This series contains a few improvements to fp-stress performance, only noticable on emulated platforms which both run more slowly and are stressed far more by fp-stress due to supporting more VLs for SVE and SME. The bulk of the improvement comes from the first patch which reduces the amount of time the main fp-stress executable is swamped by load from the child processes during startup, the other two patches are much more marginal.
