  pmc2c: inline gc write barrier into vtable methods

removed wrong UNUSED(INTERP) and UNUSED(SELF)
some methods with return values are marked TODO, need to add the write barriers manually.

A missing write barrier caused one error:
t/examples/shootout.t: 16 examples/shootout/regexdna.pir SEGV

  [pmc2c] WIP :no_wb, detection of :manual_wb, RETURN() also for VTABLE methods

add_write_barrier now calls Parrot::Pmc2c::PCCMETHOD::rewrite_RETURNs, but
this does not work yet.
