RFR(S): 8008242: VerifyOops fails on SPARC

[Morris Meyer]

Folks,

Could I get a quick follow-up review for this issue?  Christian 
Thalinger has looked this over, and it has been through JPRT.

Per Christian and Vladimir Kozlov - the getClass intrinsic is using the 
result variable which has the type T_OBJECT also as temporary which 
should have the type T_METADATA. This was okay with perm-gen but now 
this doesn't work anymore.

This is combined with my earlier displacement fixes.
