r8223 - HLL support 4

[Leopold Toetsch]

The first steps for HLL language and type support are in. You can now
dynamically load a HLL _group PMC library by just including a .HLL line
in PASM/PIR, e.g.

.HLL "Tcl", "tcl_group"
...
$P0 = new .TclInt # Integer constant

The ".HLL" pragma registers at compile time the given HLL language name
within src/hll.c and loads the given library with Parrot_load_lib().

Please note that this does not yet work for .pbc files as the HLL isn't
stored in the PBC yet (this will come soon).

See also t/dynclass/foo.t for 2 examples.

Have fun,

Should work now (rev 8224).

$ ./parrot -o f.pbc t/dynclass/foo_9.pir
$ ./parrot f.pbc

Cool. This means I don't have to do a lookup everytime I want to use one of my own types (per type per sub). Tcl will be patched shortly to take advantage.

Note that

$P0 = new TclInt

also seems to work (no dot)

Done. Thanks!
