Patch by Xianzhu Wang <wangxianzhu@chromium.org> on 2011-09-06
Reviewed by Gavin Barraclough.

Source/JavaScriptCore:

This is part of work to support 8-bit string buffers.
Adds StringBuilder::characters() because the original Vector<UChar>::data()
is widely used.
Sets the minimum size of buffer to 16 to prevent possible performance
regression. Further performance investigation should be done in
https://bugs.webkit.org/show_bug.cgi?id=67084.

* wtf/Forward.h:
* wtf/text/StringBuilder.cpp:
(WTF::StringBuilder::appendUninitialized): Sets minimum buffer size to 16 bytes.
* wtf/text/StringBuilder.h:
(WTF::StringBuilder::operator[]):
(WTF::StringBuilder::characters): Added.

Source/WebCore:

No new tests. All existing unit tests and layout tests should run
as before.
