Message:

Remove simple usage of UString::characters() from JavaScriptCore
​https://bugs.webkit.org/show_bug.cgi?id=67340

In preparation to allowing StringImpl to be backed by 8 bit
characters when appropriate, we need to eliminate or change the
usage of StringImpl::characters(). Most of the changes below
change s->characters()[0] to s[0].
