2018	Improve pmc2c to support :manual_wb flag.	bacek		"Hello.

Currently pmc2c in gen_gc branch generates automatic write barriers for:

1. VTABLEs marked with :write pragma.
2. All METHODS.

It's quite suboptimal. For example FIA.set_foo_keyed_int shouldn't trigger WB. And many of METHODs aren't mutating state of PMC.

To improve it we have to suppress generation of write barriers when pragma :manual_wb is specified.
