Fortran: fix check for pointer dummy arguments with INTENT(IN)
gcc/fortran/ChangeLog:
PR fortran/103418
* check.c (variable_check): Replace previous check of procedure
dummy arguments with INTENT(IN) attribute when passed to intrinsic
procedures by gfc_check_vardef_context.
* expr.c (gfc_check_vardef_context): Correct check of INTENT(IN)
dummy arguments for the case of sub-components of a CLASS pointer.
gcc/testsuite/ChangeLog:
PR fortran/103418
* gfortran.dg/move_alloc_8.f90: Adjust error messages.
* gfortran.dg/pointer_intent_9.f90: New test.
