RFR(s): 8218041: Assorted wrong/missing includes

[Robbin Ehn]

Hi, here is v02.

Add includes to handles.inline.hpp in all files we use a method in there.
Compiles on my 7 different configs including gcc 7.3/8.2, clang 7, no 
pre-compiled headers. And tier-1 which includes our std builds.

Also this seems to signification reduce gcc inline warnings about local comdat 
symbol for Handle(Thread*, oop).

Thanks, Robbin
