RFR (M): 8048241: Introduce umbrella header os.inline.hpp and clean up includes

[Coleen Phillimore]

Goetz,
I reviewed this change and it looks great.  Thank you for cleaning this 
up.  Since it's based on hs-gc repository, I think someone from the GC 
group should sponsor.  Otherwise, I'd be happy to.

Thanks!
Coleen
