Due to the absence of a long double version of the pow() logic function,
and due to likely little demand for ldexpl, this function has not been
specified.

The file `signalled.h` is now common to `format` and `builtin` tests.

Avoids the introduction of logic coercions with the conversions
term -> C expression -> term, by keeping the original term.

Only one split (either static or dynamic) can be active on the same term.
If a new split is encountered while a split is aleady active on the same term,
the old split is removed.
