Use a manually-synchronized HashMap instead of ConcurrentHashMap in LocaleData.
ConcurrentHashMap is our slowest choice at the moment:
ConcurrentHashMapGet 782 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
HashMapGet 272 XXXXXXXXXX|||||||||||||||
HashMapGet_Synchronized 317 XXXXXXXXXXXX|||||||||||||
HashtableGet 325 XXXXXXXXXXXX||||||||||||||
LinkedHashMapGet 280 XXXXXXXXXX|||||||||||||||
The cost of some commonly-created temporary objects (such as
DateFormatSymbols) is dominated by the lookup of the locale data. This patch
takes "new DateFormatSymbols" from 3us to 2.3us on passion/froyo (a 23% drop).
