Mike Gerwitz 85b08eb45e tamer: nir::interp: Do not include original specification in generated desc 
This is a really obvious problem in retrospect, which makes me feel rather
silly.

The output was useful, but I don't have time to deal with this any further
right now.  The comments in the commit explain the problem---that the output
ends up being interpolated as part of the fixpoint test, in an incorrect
context, and so the code that we generate is invalid.  Also goes to show why
the fixpoint tests are important.

(Yes, they're still disabled for meta-interp, I'm trying to get them
enabled.)

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.
