Why are we pushing this onto the M49 branch? We only need the ios changes on
trunk ...

Just for the record (although I told Dirk offline):  My choice of the branch
name was confusing and unfortunate. 'm49' here had better been named 'icu54'. 
This revision will NOT be used in CHromium's M49 branch.  This will be used only
in Chrome's trunk.
