There's no need to store parser error messages for states with
depth > 0, as they will eventually be popped from the states stack and
their error messages will never be displayed to the user.
Profiling shows that this change reduces the % of backtraces that
contain the store_state & load_state functions from ~95% to ~70%.
Empirically this change reduces the time it takes on my machine for the
c++ language server to handle a file that #includes <LibGUI/Widget.h>
from ~14sec to ~4sec.
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).
We can now handle access-specifier tags (for example 'private:') when
parsing class declarations.
We currently only consume these tags on move on. We'll need to add some
logic that accounts for the access level of symbols down the road.
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.
After this commit, Parser::index_of_node_at will prefer to return nodes
with greater indices.
Since the parsing logic ensures that child nodes come after parent
nodes, this change makes this function return child nodes when possible.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

This was done with the `ambr` search and replace tool.

This type represents templatized names, and replaces our previous use
of 'TemplatizedType' and 'TemplatizedFunctionCall'.
Also, we now parse function calls as secondary expressions.
After we moved to storing the text of each token in the token itself,
we no longer have to store the source of the program in the Parser.
This makes more sense because the parser should deal with tokens, not
with raw source code.
