RFR: 8134389: Crash in HotSpot with jvm.dll+0x42b48 ciObjectFactory::create_new_metadata

[Jamsheed C m]

Hi All,

bugid: https://bugs.openjdk.java.net/browse/JDK-8134389

webrev: http://cr.openjdk.java.net/~jcm/8134389/webrev.00/

return type information is not available in lforms, this causes 
contradictions in operation like  store indexed. mh _linkTo* site arg 
type casting. etc..

fix: TypeCast to declared return type at lform return.

Best Regards,

Jamsheed
