seems like these asserts should be debug only

[please use gerrit instead, 2014/01/06 23:44:35]

These asserts do not trigger in Release mode (I've tried), but I haven't been
able to find the code in Chrome that specifies #define NDEBUG in Release mode.

If you want to be extra sure that these asserts do not trigger in Chrome's
release builds, we can add a LIBADDRESSINPUT_ASSERT macro. We can customize this
macro in our own libaddressinput.gyp file.

Which option do you prefer? (leave as-is vs. macro)
