All attributes now get parsed, let's see what happens. Main goals here:

• figure out how often macro_escape is used
• figure out which warnings are widely reported and note that in a comment
• if some warnings are never or very rarely emitted, let's see if that can be turned into an error
• this parses attributes on macro calls together, I wonder if that matters.

(repr combinations/no_mangle/export_name are not included, they are covered in other crater runs)

r? @JonathanBrouwer, can you double check? I might've overlooked stuff.

Let's see whether rustc can bootstrap on linux with these changes
