Roll ICU to eda9e75b to add the Windows data dll

v8 still uses the data dll (icudt.dll) on Windows.

While building the Windows data dll, a few issues were discovered in
the ICU data that were overlooked. Only one of them (the display name
for Moldovan in Moldovan) is user-visible.

ICU ( eda9e75b1fa17f57ffa369ee3543a2301b68d0a9 ) has fixes for them.

In addition, fix the display name for 'mo' (which is actually 'ro-MD')
and add a test.  It's "broken" ever since ICU upgrade to 54.1. (See http://bugs.icu-project.org/trac/ticket/11563 )
