Initial infrastructure for fast compilation of top-level code. The fast code generator is optimized for compilation time and code size. Currently it is only implemented on IA32. It is potentially triggered for any code in the global scope (including code eval'd in the global scope). It performs a syntactic check and chooses to compile in fast mode if the AST contains only supported constructs and matches some other constraints. Initially supported constructs are * ExpressionStatement, * ReturnStatement, * VariableProxy (variable references) to parameters and stack-allocated locals, * Assignment with lhs a parameter or stack-allocated local, and * Literal This allows compilation of literals at the top level and not much else. All intermediate values are allocated to temporaries and the stack is used for all temporaries. The extra memory traffic is a known issue.
