fix additional semicolon during changing parentheses style

[rscprof]

#6013

Prevent add semicolon when changing parentheses style when using lazy_static. If we see that previous parentheses is round and we use the rule for lazy_static then we set flag about it and after it we simple skip insert semicolon during postprocessing spaces and semicolon.

Hi @ytmimi, I thought about returning pair, but I thought that it changes functions signatures drastically. I will change it tomorrow in your way.

@rscprof Can you take a look at the failures when you have a chance. Also, the rustfmt team strongly discourages merge commits. When you have a moment can you rebase these changes instead.

@rscprof I'm still seeing the Merge branch 'master' into issue-6013 commit in the history. Can you please update the git history to remove that merge commit.
