Comparing c_ptr type for equality or inequality is raising an error. ``` not yet implemented: intrinsic module procedure: c_ptr_eq ``` or this one for inequality ``` not yet implemented: intrinsic module procedure: c_ptr_ne ``` This patch adds a lowering for them and fix the `__fortran_builtins.f90` module for inequality. Reland after fix has landed for circular modules #85309
