[fullcodegen] Remove dead hole check logic

[fullcodegen] Remove dead hole check logic

Variables requiring initialization are already forced into ignition,
so all the code supporting hole checks in full-codegen and
ast-graph-builder is dead.

Actually, seems like we should remove all code for hole checks in full-codegen
and AstGraphBuilder, will update this patch...

This patch doesn't touch AstGraphBuilder, but removes all hole check logic from
full-codegen.
