Become a little smarter with formatting long chains of pipes.
Assign a high penalty to breaking before "<<" if the previous token is a
string literal ending in ":" or "=".
Before:
llvm::outs()
<< "aaaaaaaaaaaaaaaaa = " << aaaaaaaaaaaaaaaaa << "bbbbbbbbbbbbbbbbb = "
<< bbbbbbbbbbbbbbbbb << "ccccccccccccccccc = " << ccccccccccccccccc
<< "ddddddddddddddddd = " << ddddddddddddddddd << "eeeeeeeeeeeeeeeee = "
<< eeeeeeeeeeeeeeeee;
After:
llvm::outs() << "aaaaaaaaaaaaaaaaa = " << aaaaaaaaaaaaaaaaa
<< "bbbbbbbbbbbbbbbbb = " << bbbbbbbbbbbbbbbbb
<< "ccccccccccccccccc = " << ccccccccccccccccc
<< "ddddddddddddddddd = " << ddddddddddddddddd
<< "eeeeeeeeeeeeeeeee = " << eeeeeeeeeeeeeeeee;
