<pre>A simple unit test:
TEST(APFloatTest, x87Largest) {
APFloat MaxX87Val = APFloat::getLargest(APFloat::x87DoubleExtended);
EXPECT_TRUE(MaxX87Val.isLargest()); // Don't crash.
}
Causes an assertion failure in APFloat::isSignificandAllOnes():
assert(NumHighBits <= integerPartWidth &&
"Can not have more high bits to fill than integerPartWidth");</pre>
