    fortran: Support clobbering of allocatables and pointers [PR41453]

    This adds support for clobbering of allocatable and pointer scalar
    variables passed as actual argument to a subroutine when the associated
    dummy has the INTENT(OUT) attribute.
    Support was explicitly disabled (since the beginning for pointers, since
    r11-7315-g2df374b337a5f6cf5528e91718e4e12e4006b7ae for allocatables),
    but the clobber generation code seems to support it well, as
    demonstrated by the newly added testcase.

            PR fortran/41453
            PR fortran/99169

    gcc/fortran/ChangeLog:

            * trans-expr.cc (gfc_conv_procedure_call): Remove conditions
            on ALLOCATABLE and POINTER attributes guarding clobber
            generation.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/intent_optimize_9.f90: New test.=
