CoercionForm how to display a node that could have come from a cast

NB: equal() ignores CoercionForm fields, therefore this must not carry any semantically significant information. We need that behavior so that the planner will consider equivalent implicit and explicit casts to be equivalent. In cases where those actually behave differently, the coercion function's arguments will be different.

Variants

COERCE_EXPLICIT_CALL

COERCE_EXPLICIT_CAST

display as a function call

COERCE_IMPLICIT_CAST

display as an explicit cast
