Formatter: No space after & and * in front of ObjC message expressions.
1. let determineStarAmp() check of unary operators before checking for
"is next '['". That check was added in r173150, and the test from that
revision passes either way.
2. change determineStarAmp() to categorize '*' and '&' after '=' as unary
operator.
3. don't let parseSquare() overwrite the type of a '*' or '&' before the start
of an objc message expression if has the role of unary operator.
