Check in the pristine copy of ICU 52.1
The following directories we don't use are removed:
as_is
packaging
source/layout
source/layoutex
Better plural formatting, updated locale data, the segmentation support
for Chinese, Japanese (our code was upstreamed) and Khmer/Lao are among
many improvements. EcmaScript I18N API also need this update to be compliant
to the spec.
Because codereview.chromium.org keeps giving me a 500 error when uploading
the CL, so this initial check-in is done directly with svn.
BUG=132145
