Backport of upstream revision 56345 (2010-03-22 Darin Adler <darin@apple.com>)
to webkit-gtk-1.1.15.4

TextBreakIteratorICU.cpp is incompatible with new UBreakIterator type in ICU 4.4
https://bugs.webkit.org/show_bug.cgi?id=36381
platform/text/TextBreakIteratorICU.cpp, platform/text/TextBoundariesICU.cpp:
Use reinterpret_cast instead of static_cast or relying on conversion to void*.
