[ic] Use StrictEqual/Equal builtins for CompareIC slow path.

[ic] Use StrictEqual/Equal builtins for CompareIC slow path.

Don't fallback to the %StrictEqual / %Equal runtime functions for the
generic CompareIC slow path, but use the (new) StrictEqual and Equal
builtins instead. This avoids a performance cliff when mixing input
types for strict equality sites.
