RFR(T) 8203005: The top-of-stack type specified for nofast_* bytecodes are wrong

[Yumin Qi]

Hi, please review the tiny changes for

bug: https://bugs.openjdk.java.net/browse/JDK-8203005

webrev:http://cr.openjdk.java.net/~minqi/2020/8203005/webrev-00/


Summary: The change was left by 
8074345(https://bugs.openjdk.java.net/browse/JDK-8074345), the types 
were wrongly put as T_ILLEGAL for T_OBJECT, and T_ILLEGAL for T_INT. 
This has not triggered any failures yet since the types stored in the 
type array for nofast version are never used, the used types are always 
the original types fortunately(unfortunately either).


tests: tier1,tier2,tier3


Thanks

Yumin
