Shane, you fixed an integer overflow in September and ICU 63.1 has that fix. This one seems to be a new one. Once I reproduce it, I'll file an upstream bug if it's not already known/fixed. 

Hmmm... this one is similar to https://unicode-org.atlassian.net/browse/ICU-20037 which had been  fixed before ICU 63.1 was released.

Roll ICU to 834113

It has two changes:

https://chromium.googlesource.com/chromium/deps/icu.git/+log/42d5027..834113

One is to cherry-pick an integer overflow fix. The other is to fix
ISO-2022-JP encoding.

Now that 373 code points are encoded as expected. Rebaseline the test results
(delete them because all the code points in those files pass).
