  Log Message:
  -----------
  [pmc2c] inline gc write barriers into vtable methods

:no_wb detection of :manual_wb, allow RETURN(decl var) also for VTABLE methods

add_write_barrier() now calls Parrot::Pmc2c::PCCMETHOD::rewrite_RETURNS.
Also add automatic WB for 0 or 1 return statements in the method body.
Other need either a RETURN or :manual_wb or :no_wb annotations.

Set manual_wb for :no_wb and PARROT_GC_WRITE_BARRIER in --dump
Detect it now earlier, in the parser

Missing write barriers typically cause the following errors:
t/examples/shootout.t: 16 examples/shootout/regexdna.pir SEGV
t/op/gc.t
t/pmc/*.t

  [pmc2c] support RETURN(PMC* const ...) and (INTVAL pos>>32)

const is no variable name.
allow full expressions as return value, not just names.

just skip ptr dereferences /^\**/. Note that the * return syntax is flawed,
as we should support both cases, return *ptr; and return ptr;
But we get away with it as we return only return (decl)*ptr and return (decl*)ptr;
