Support ASL version 1.0

Extensive changes to ASLi

Changes include:

• Change ASLi to support most of ASL version 1.0 requiring significant changes to the AST, lexer, parser and typechecker.
• Cleanup the "CPU" API that ASLi expects an ISA to implement.
• Add support for compiling ASL specifications to C by adding many transformations and multiple runtimes.
• Add a demo ISA to illustrate how to generate simulators from an ASL specification.
