Begin overhauling semantic phases This change further merges the new AST and MuPack/MuIL formats and abstractions into the core of the compiler. A good amount of the old code is gone now; I decided against ripping it all out in one fell swoop so that I can methodically check that we are preserving all relevant decisions and/or functionality we had in the old model. The changes are too numerous to outline in this commit message, however, here are the noteworthy ones: * Split up the notion of symbols and tokens, resulting in: - pkg/symbols for true compiler symbols (bound nodes) - pkg/tokens for name-based tokens, identifiers, constants * Several packages move underneath pkg/compiler: - pkg/ast becomes pkg/compiler/ast - pkg/errors becomes pkg/compiler/errors - pkg/symbols becomes pkg/compiler/symbols * pkg/ast/... becomes pkg/compiler/legacy/ast/... * pkg/pack/ast becomes pkg/compiler/ast. * pkg/options goes away, merged back into pkg/compiler. * All binding functionality moves underneath a dedicated package, pkg/compiler/binder. The legacy.go file contains cruft that will eventually go away, while the other files represent a halfway point between new and old, but are expected to stay roughly in the current shape. * All parsing functionality is moved underneath a new pkg/compiler/metadata namespace, and we adopt new terminology "metadata reading" since real parsing happens in the MetaMu compilers. Hence, Parser has become metadata.Reader. * In general phases of the compiler no longer share access to the actual compiler.Compiler object. Instead, shared state is moved to the core.Context object underneath pkg/compiler/core. * Dependency resolution during binding has been rewritten to the new model, including stashing bound package symbols in the context object, and detecting import cycles. * Compiler construction does not take a workspace object. Instead, creation of a workspace is entirely hidden inside of the compiler's constructor logic. * There are three Compile* functions on the Compiler interface, to support different styles of invoking compilation: Compile() auto- detects a Mu package, based on the workspace; CompilePath(string) loads the target as a Mu package and compiles it, regardless of the workspace settings; and, CompilePackage(*pack.Package) will compile a pre-loaded package AST, again regardless of workspace. * Delete the _fe, _sema, and parsetree phases. They are no longer relevant and the functionality is largely subsumed by the above. ...and so very much more. I'm surprised I ever got this to compile again!
