Use the single char overload of append() when possible.

We should use StringBuilder::append(LChar) or String::append(LChar) when
possible since it produces smaller code and is faster. I also switched
some code that was calling String::append() repeatedly to use
StringBuilder instead to avoid the repeated copies.
