[14]RFR 8180392: SunJCE provider should throw exceptions for unsupported mode and padding combinations

[Valerie Peng]

Anyone have spare cycles to review this fix? Fix is straight forward - 
instead of relying on the supported mode and padding info from provider, 
javax.crypto.Cipher class now instantiates the CipherSpi object to make 
sure the particular mode and padding combination is supported.
