attr: do not attempt to expand when we know it's not a macro
Keep track of all recognized macros in the new "maybe_macro" field. If this field is true, it _may_ be a macro (depending on what's in the current attr stack). But if the field is false, it's definitely not a macro, no need to go through the whole attr stack in macroexpand_one() to search for one. Without this, "git grep abcdefghi" on git.git hits the inner loop in macroexpand_one() 2481 times. With this, it's 66 times.
