[turbofan] Move Number.isFinite to JSCallReducer
...
This also introduces two new simplified operators,
NumberIsFinite and ObjectIsFiniteNumber; the latter
handles all values, and the former is a fast-path
of the fast-path that is inserted by typed optimization
if we know the input has Type::Number.

[turbofan] Inline promise constructor in turbofan.
...
Inline the promise constructor when we have one argument and target
matches new_target.
This is not complete, and is sitting behind an experimental flag for
now. We need to fix deoptimization by providing proper frame states.
Create a unittest class for JSCallReducer - just assert whether there
was a change or not, rather than specify the exact graph that should be
produced.
