Improve pmc2c to support :manual_wb flag.

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.

gen_gc branch now have support for :manual_wb on VTABLEs. FIA is sample how it's can be used.

Awesome. Once it's documented and the branch is merged into master, we can close this ticket.

Not so fast. Support for METHODs isn't there yet :)
