The other aspects of the configurations that have been modified have been non-critical. Where appropriate, brief rationales are recorded. This resolves an old TODO item in the post-submit matrix. Fixed a sign mismatch in initializing an OpenCL variable that didn't need to be initialized. Noted relevant new TODOs.

Since this is a range we really don't care about, and non-FMA platforms are anyway a thing of the past, just avoid testing a very small range around that threshold for non-FMA SIMD platforms. Fixes #2335.
