Previously almost all fields were public and were directly accessed by
the Parser and CppComprehensionEngine.
This commit makes all fields of AST node types private. They are now
accessed via getters & setters.
This adds a new ASTNode type called 'NamedType' which inherits from
the Type node.
Previously every Type node had a name field, but it was not logically
accurate. For example, pointer types do not have a name
(the pointed-to type may have one).
Previously, we had a special ASTNode for class members,
"MemberDeclaration", which only represented fields.
This commit removes MemberDeclaration and instead uses regular
Declaration nodes for representing the members of a class.
This means that we can now also parse methods, inner-classes, and other
declarations that appear inside of a class.
Previously, ASTNode::dump() used outln() for output, which meant it
always wrote its output to stdout.
After this commit, ASTNode::dump() receives an 'output' argument (which
is stdout by default). This enables writing the output to somewhere
else.
This will be useful for testing the LibCpp Parser with the output of
ASTNode::dump.

This type represents templatized names, and replaces our previous use
of 'TemplatizedType' and 'TemplatizedFunctionCall'.
Also, we now parse function calls as secondary expressions.
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
This parser will be used by the C++ langauge server to provide better
auto-complete (& maybe also other things in the future).
It is designed to be error tolerant, and keeps track of the position
spans of the AST nodes, which should be useful later for incremental
parsing.
