bazel syntax: simplify comprehensions
This change merges {List,Dict,Abstract}Comprehension into a
single concrete class. The "k: v" body in a dict comprehension
{k: v for vars in iterable} is now represented as
DictionaryLiteral.Entry.
"Clause" was a poor abstraction: clients need to know that
there are only two instances, If and For, and handle them
specifically.
The doEval method is now a single recursive
function that fits easily in a single page.
We delete the following classes:
AbstractBuilder
OutputCollector
ListComprehension
Builder
ListOutputCollector
Clause.Kind
DictComprehension
Builder
DictOutputCollector
