BUG=v8:2943
LOG=Y
TEST=Unit tests for "real life" use cases, edge cases, various types of normalization.
==========================
This is identical to the previous CL
https://codereview.chromium.org/40133004/
with two differences:
* Added a dummy implementation of String.prototype.normalize to be used when v8 is compiled without intl support
* Rebased the the test files for webkit. That was the only reason for the previous failure (and revert).
Thank you,
Mihai
