I backport this for parity with 11.0.15-oracle.

The patch does not apply well.

8259842: Remove Result cache from StringCoding  is missing in 11.
Therefore the actual change must be applied to StringCoding.java
and not to String.java.  The method encodeUTF8_UTF16() was moved
from the one to the other file in 8259842.

8259842 change also brought the benchmark edited by this change.
I include the whole benchmark in this change.
