We missed one place which loads java method's pointer (old MethodOop) from 
vtable when switched to NPG. The load is marked as oop load and as result 
method's pointer (which is in Metaspace now) ends up in oopmap.

I did not find any more similar places. But I found incorrect switch code which 
I fixed.

Note, diffs does not show indent change in compile.hpp:

Thanks,
