Bind(C): Correct sizes of some types in CFI_establish
CFI_establish was failing to set the default elem_len correctly for
CFI_type_cptr, CFI_type_cfunptr, CFI_type_long_double, and
CFI_type_long_double_Complex.

* runtime/ISO_Fortran_binding.c (CFI_establish): Special-case
CFI_type_cptr and CFI_type_cfunptr. Correct size of long double
on targets where it has kind 10.
