Message:

Added a bmalloc back-end for FastMalloc
​https://bugs.webkit.org/show_bug.cgi?id=131387

Reviewed by Andreas Kling.

We'll need to rethink some things if we adopt this back-end. For example,
fastMallocSize() and fastMallocGoodSize() are no longer real things. But,
this is enough to test for now.

• wtf/FastMalloc.cpp:

(WTF::fastMalloc):
(WTF::fastCalloc):
(WTF::fastRealloc):
(WTF::fastFree):
(WTF::fastMallocSize):
(WTF::fastMallocGoodSize):
(WTF::tryFastMalloc):
(WTF::tryFastRealloc):
(WTF::tryFastCalloc):
(WTF::releaseFastMallocFreeMemory):
(WTF::fastMallocStatistics):
