RFR: 8229836: Remove include of globals.hpp from allocation.hpp

[Stefan Karlsson]

Hi all,

Please review this patch to remove the include of globals.hpp from 
allocation.hpp.

http://cr.openjdk.java.net/~stefank/8229836/webrev.01/
https://bugs.openjdk.java.net/browse/JDK-8229836

Note this change is just the bare minimum to get it to compile on our 
build platforms. I haven't tried to find all files that are missing 
explicit includes of globals.hpp.

Thanks,
StefanK
