Some type-check/type-cast functions start with "Is" or "To".
e.g. IsHTMLElement(), ToHTMLElement()
However, some type-check/type-cast functions start with "is" or "to".
e.g. isHTMLInputElement(), toHTMLInputElement().
Generated code defines the latter. See Source/core/build/scripts/make_element_type_helpers.py and Source/core/build/scripts/templates/ElementTypeHelpers.*.tmpl.
