Fortran: do not pass hidden character length for TYPE(*) dummy [PR110825]
gcc/fortran/ChangeLog:
PR fortran/110825
* gfortran.texi: Clarify argument passing convention.
* trans-expr.cc (gfc_conv_procedure_call): Do not pass the character
length as hidden argument when the declared dummy argument is
assumed-type.
gcc/testsuite/ChangeLog:
PR fortran/110825
* gfortran.dg/assumed_type_18.f90: New test.
