Reviewer needed: backport of "6371401: java.math.BigInteger.shift(Integer.MIN_VALUE) throws StackOverflowError" into IcedTea6 HEAD

[Pavel Tisnovsky]

Greetings,

here's another fix from OpenJDK7 I'd like to backport to IcedTea6 HEAD:
"6371401: java.math.BigInteger.shift(Integer.MIN_VALUE) throws
StackOverflowError"

This patch contains fix for BigInteger class and also regression test.
The behaviour of BigInteger was tested on RHEL 5 x86_64.
