[lang] Add new function templates for pure functions.

The new supported functions names are: `compare`, `compareTo`, `abs`,
`acos`, `asin`, `atan`, `atan2`, `cbrt`, `ceil`, `cos`, `cosh`, `exp`,
`floor`, `hypot`, `log`, `log10`, `log1p`, `max`, `min`, `pow`,
`random`, `rint`, `round`, `scalb`, `signum`, `sin`, `sinh`, `sqrt`,
`tan`, `tanh`, `ulp`.
