    Fortran - ICE in inline_matmul_assign

    Restrict inlining of matmul to those cases where assignment to the
    result array does not need special treatment.

    gcc/fortran/ChangeLog:

            PR fortran/99839
            * frontend-passes.c (inline_matmul_assign): Do not inline matmul
            if the assignment to the resulting array if it is not of canonical
            type (real/integer/complex/logical).

    gcc/testsuite/ChangeLog:

            PR fortran/99839
            * gfortran.dg/inline_matmul_25.f90: New test.
