8262028: Make InstanceKlass::implementor return InstanceKlass

[hseigel]

Please review this small fix to change the parameter and return types from Klass* to InstanceKlass* in the InstanceKlass::*implementor() functions.

The fix was tested with Mach5 tiers 1 and 2 on Linux, Mac OS, and Windows, and tiers 3-5 on Linux x64.

Thanks, Harold
