JDK-4261803 - Need an unsynchronized StringBuffer
Description
The BigDecimal and BigInteger classes were written to use StringBuffer's internally while generating a String to output.  Since all the operations on those StringBuffers occur within a single method and the StringBuffer does not escape the method, these uses of StringBuffer should be replaced with the unsynchronized StringBuilder.
