Massive reworking of the entire front end for performance and clarity: - switch-based lexer with optimizations for common cases - unthreading of the token stream in the parser - removal of debugging calls in parser (the compiler could insert this code) - lexer/parser interface has limited-length token queue, avoiding consing - concretization of token representation to avoid function calls on critical path - hash tables instead of linear lists to hash cons (!) tokens - allow esc.es to compile multiple files in one go to avoid JIT warmup - and more This patch assumes that #416248 has been applied. It subsumes #416249.
