832e9c6e02 LibCpp: Add regression tests for the parser 
For each .cpp file in the test suite data, there is a .ast file that
represents the "known good" baseline of the parser result.

Each .cpp file goes through the parser, and the result of
invoking `ASTNode::dump()` on the root node is compared to the
baseline to find regressions.

We also check that there were no parser errors when parsing the .cpp
files.

402483ec1f LibCpp: Generalize ASTNode::dump() to support redirecting its output 
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.

0e51aea781 LibCpp: Modify parsing of a Name's scope 
A Name node can now have a non-empty scope and a null name.

For example, "AK::" has a non-empty scope and a null name component.

84e41c4565 LibCpp: Modify logic of Parser::index_of_node_at 
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.

What happens if one file defines DEBUG_SPAM, and another doesn't,
then we link them together and get ODR violations? -- @ADKaster

b91c49364d AK: Rename adopt() to adopt_ref()

SPDX License Identifiers are a more compact / standardized
way of representing file license information.

5b22f6f45a LibCpp: Parser no longer holds the program's source 
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.
