WTF_USE_LOCKFREE_THREADSAFEREFCOUNTED is defined in wtf/Atomic.h, which should be in Platform.h
Can you please provide the rationale? We have most USE macros defined in Platform.h indeed, but it's not great to dump them all together in one file. So, I'm honestly unsure if this would be an improvement.

So, I'm honestly unsure if this would be an improvement. see https://bugs.webkit.org/show_bug.cgi?id=89428#c16 there may be some misunderstanding in the bug #89428, peter asked me to put a MACRO in platform.h instead of Atomic.h. I misunderstood him and thought we shoudl put all MACRO in platform.h instead of Atomics.h. please ignore this bug entry. thanks
