When FMA is not supported by the hardware, these methods fall back to
BigDecimal usage which causes them to be 2500x slower.
While most hardware in the last 10 years may have the support, out of
box both VirtualBox and QEMU don't pass thru FMA support (for the latter
at least you can tweak it with e.g. -cpu host or similar to fix this).
This creates a terrible undocumented performance trap. Prevent it from
sneaking into our codebase.
These are easy/obvious ones to disable since we don't use the
functionality at all: the checks are literally useless.
This gives some performance boost to the error-prone, although it is
still pretty slow.
triage most of the previously disabled checks into TODO, noisy, etc
