Add a cache to Currency.getInstance(Locale).
Statically there are lots of calls to Currency.getInstance(String) in the
core libraries and only one to Currency.getInstance(Locale). This might
be why the former has a cache but the latter doesn't. Dynamically, looking
up Currency by Locale is a common operation because that one caller --
DecimalFormatSymbols -- is widely used, and it sets up its currency data
eagerly. (Which might be worth coming back and also fixing later.)

Cache NumberFormat and DecimalFormatSymbols objects in a ThreadLocal,
so they can be reused between multiple instances of Formatter on the
same thread. This speeds up my unscientific benchmark (a number of
printouts involved in a debugging diagnostics output) by 3x, and
should have a similar impact on anyone who uses String.format(),
PrintWriter.format(), and the like.
