<i18n dev> Review Request for CR : 7050528 Improve performance of java.text.DecimalFormat.format() call stack

[Olivier Lagneau]

Please review The implementation of a fast-path algorithm for optimizing 
the DecimalFormat.format(double, ...) call stack.

The webrev is here :
http://cr.openjdk.java.net/~olagneau/7050528/webrev.02/

As described in the CR evaluation and suggested fix, the speed-up on a 
dedicated micro-benchmark
is more than x10 on either SPARC or x86 architectures. The footprint 
cost is ~6kbytes from a static
char array constant data to collect digits from integer values.

There is an associated regression test, together with a micro-benchmark 
that may be run optionally.
