ASSOCIATE (ptr, tgt) takes as first argument also an assumed-rank array;
however, using it together with a tgt (required to be non assumed rank)
had issues for both scalar and nonscalar tgt.
PR fortran/101334
gcc/fortran/ChangeLog:
* trans-intrinsic.c (gfc_conv_associated): Support assumed-rank
'pointer' with scalar/array 'target' argument.
libgfortran/ChangeLog:
* intrinsics/associated.c (associated): Also check for same rank.
gcc/testsuite/ChangeLog:
* gfortran.dg/associated_assumed_rank.f90: New test.
