  Log Message:
  -----------
  [flang] Warn when F128 is unsupported (#102147) (#106957)

This generates `warning: REAL(KIND=16) is not an enabled type for this
target` if that type is used in a build not correctly configured to
support this type. Uses of `selected_real_kind(30)` return -1.

Relanding #102147 because the test errors turned out to be specific to a
downstream configuration.
