loadLoadFence should use dmb ishld

Reviewed by Yusuke Suzuki.
Use the load-only variant of dmb where available i.e. ARM64. We only use
loadLoadFence in our code today but the same barrier works for
loadStoreFence.
* Source/JavaScriptCore/API/tests/VMManagerStopTheWorldTest.cpp:
(VMManagerStopTheWorldTest::WTF_REQUIRES_LOCK):
At first glance this seems to be a storeLoadFence, it's also test
code so there's not really any reason to be less conservative.
* Source/WTF/wtf/CountingLock.h:
Update the comment so it doesn't claim to use dmb ish.
