This introduces the ability to specify an edge ordering for the ontological tree traversal. `tree_reconstruction` will now use a `SourceCompatibleTreeEdgeOrder`, which will traverse the graph in an order that will result in a properly ordered source reconstruction. This is needed for template headers, because interpolation causes metavariables (exposed as template params) to be mixed into the body. There's a lot of information here, including some TODOs on possible improvements. I used the unstable `is_sorted` to output how many template were already sorted, based on one of our very large packages internally that uses templates extensively, and found that none of the desugared shorthand template expansions were already ordered. If I tweak that a bit, then nearly all templates will already be ordered, reducing the work that needs to be done, leaving only template definitions with interpolation to be concerned about, which is infrequent relative to everything else.

XMLI System Test
The xmli file is an intermediate file that serves as a handoff between
TAMER and the XSLT-based compiler:
xml -> (TAMER) -> xmli -> (TAME XSLT) -> xmlo
TAMER gets the first shot at processing, and then the compilation process continues with the XSLT-based compiler. This allows TAMER to incrementally augment and manipulate the source file and remove responsibilities from TAME XSLT.
Tests in this directory ensure that this process is working as intended. TAMER's failure to perform a proper handoff will cause TAME XSLT to compile sources incorrectly, since TAMER will have rewritten them to something else.
This handoff is more than just echoing tokens back into a file---it derives a new program from the state of the ASG. This program may have a slightly different representation than the original sources, but it must express an equivalent program, and the program must be at least as performant when emitted by TAME XSLT.
Experimental Features
If a file is-experimental exists in a test directory, then
--emit xmlo-experimental will be used in place of --emit xmlo.
Running Tests
Test are prefixed with test-* and are executable. They must be invoked
with the environment variable PATH_TAMEC set to the path of tamec
relative to the working directory.
Test cases are organized into sub-directories with src.xml and
expected.xml files. src.xml will be compiled with tamec, its output
formatted with xmllint --format, and diff'd against the
xmllint-formatted output of expected.xml.
