JDK-8254335 - logging/logStream.hpp includes memory/resourceArea.hpp but doesn't need it
Description
During VM initialization, before Thread::current() works, any resource allocation is prohibited. This means that classes like LogStream and LogStreamNoResourceMark can't be used.

I propose that we add a new LogStream class that allocates the backing buffer in CHeap memory.
Comments
Patch is out for review on hotspot-dev.
