* Basic grammar and parser for the Fix language. We use libsglr and friends to do the parsing. The parse table is embedded in the Fix executable using bin2c, which converts an arbitrary file into a C character array.

* Use a map to lookup primops. * Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
