Mike Gerwitz 82915f11af tamer: asg::graph::object::xir: Initial rate element reconstruction
This extends the POC a bit by beginning to reconstruct rate blocks (note
that NIR isn't producing sub-expressions yet).

Importantly, this also adds the first system tests, now that we have an
end-to-end system.  This not only gives me confidence that the system is
producing the expected output, but serves as a compromise: writing unit or
integration tests for this program derivation would be a great deal of work,
and wouldn't even catch the bugs I'm worried most about; the lowering
operation can be written in such a way as to give me high confidence in its
correctness without those more granular tests, or in conjunction with unit
or integration tests for a smaller portion.

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.

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.
