[dev.ssa] cmd/compile/ssa: separate logging, work in progress, and fatal errors The SSA implementation logs for three purposes: * debug logging * fatal errors * unimplemented features Separating these three uses lets us attempt an SSA implementation for all functions, not just _ssa functions. This turns the entire standard library into a compilation test, and makes it easy to figure out things like "how much coverage does SSA have now" and "what should we do next to get more coverage?". Functions called _ssa are still special. They log profusely by default and the output of the SSA implementation is used. For all other functions, logging is off, and the implementation is built and discarded, due to lack of support for the runtime. While we're here, fix a few minor bugs and add some extra Unimplementeds to allow all.bash to pass. As of now, SSA handles 20.79% of the functions in the standard library (689 of 3314).
