Remove deprecated functionality This removes a large array of deprecated functionality, regardless of how recently it was deprecated. The purpose of this commit is to clean out the standard libraries and compiler for the upcoming alpha release. Some notable compiler changes were to enable warnings for all now-deprecated command line arguments (previously the deprecated versions were silently accepted) as well as removing deriving(Zero) entirely (the trait was removed). The distribution no longer contains the libtime or libregex_macros crates. Both of these have been deprecated for some time and are available externally.

Make lexer tooling message more generic We don't actually probe for javac in all circumstances, so if you have javac installed, but don't have antlr4 installed, and you're on Mac OS X, then you'll get a message that javac is missing, even though that's wrong. To fix this, let's just be a bit more generic in the message, so that it's the same no matter what part of the lexer tests you're missing. cc https://www.reddit.com/r/rust/comments/3m199d/running_make_check_on_the_source_code_says_javac/
