  -----------
  [flang] Inner INTRINSIC must not shadow host generic

A generic interface (however spelled) can have the same name as
an intrinsic procedure in the same scope.  When an explicit INTRINSIC
attribute statement appears in a nested scope, semantics was
unconditionally declaring a new symbol that hid the generic entirely.
Catch this case and create instead a host association symbol for
the generic that can then be decorated with the INTRINSIC attribute.
