Enable RTTI for ICU.
ICU 4.6 uses RTTI (dynamic_cast and typeid) in many places.
It'll increase the vtbl size. I'm gonna measure the size impact by
making two builds:
1. With rtti enabled
2. With rtti disabled, but with dynamic_cast replaced with
static_cast and typeid with 'something' buildable. This build wouldn't run
properly, but for the size comparision, just compiling it should be fine.
On Windows, we set _HAS_EXCEPTIONS to 0 in common.gypi. To build ICU
without enabling exception as well on Windows, we replaced the following line
#include <typeinfo>
with
#include "unicode/utypeinfo.h"
and add a new file 'common/unicode/utypeinfo.h' with the following:
#if defined(_MSC_VERSION) && _HAS_EXCEPTIONS == 0
#include <exception>
using std::exception;
#endif
#include <typeinfo>

TEST=On all 3 platforms, Chrome can be built and can be run without crash.
