Dmitriy Dumanskiy b72fea340b Improve DateFormatter parsing performance (#8821) ... Motivation: Just was looking through code and found 1 interesting place DateFormatter.tryParseMonth that was not very effective, so I decided to optimize it a bit. Modification: Changed DateFormatter.tryParseMonth method. Instead of invocation regionMatch() for every month - compare chars one by one. Result: DateFormatter.parseHttpDate method performance improved from ~3% to ~15%.
