Treat OP_F77_UNDETERMINED_ARGLIST as OP_FUNCALL
When I debug some fortran expression parsing, I got
(gdb) set debug expression 1
(gdb) p intvla(5,5,5)
Dump of expression @ 0x205fa80, before conversion to prefix form:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This patch fixes this problem by handling OP_F77_UNDETERMINED_ARGLIST in
the same way as handling OP_FUNCALL. With this patch applied, the output
looks better,
(gdb) p intvla (5,5,5)
