BUILD_ERROR() is even stronger a guard than assertions in general, and
ASSERT_UNREACHABLE() (or BUG()) in particular. Deviate it just like those
to allow use for marking unreachable portions of code.
In some cases code being unreachable is dependent upon configuration.
Introduce two variants, as constructs like
if ( IS_ENABLED(CONFIG_...) )
BUILD_ERROR("...");
results in the if() still being reported as unreachable. Sadly these two
new macros introduce a new 20.12 violation each, which hence also needs
deviating.
