  TZone: Implement TZone Allocation on JavaScriptCore Types
https://bugs.webkit.org/show_bug.cgi?id=268673
rdar://122213822

Reviewed by Keith Miller.

This patch implements TZone selection in bmalloc through the newly added TZoneHeapManager class.
The macro that defines a TZone allocated type puts the type name, type size and type aligment in a static bmalloc_type.
That static object is now placed in a newly added __DATA_CONST$__tzone_descs section.  At startup time, each dylib / framework
will register their types by passing this new section's start and end location to the TZoneHeapManager::registerTZoneTypes() method.
When allocating a type for the first time, TZoneHeapManager will allocate if needed for all buckets for the same size and alignment.
Then the manager will compute which of those bucket to use the current type.  This is computed by a process start up seed and the
size and type.

The JavaScript types have been annotated and all JavaScript tests run.  DumpRenderTree has been modified as well.

This patch has TZone allocation turned off via BUSE_TZONE in bmalloc/BPlatform.h and USE_TZONE_MALLOC in wtc/PlatformUse.h
The BUSE_TZONE macro was added to work around a linker bug where unused exported functions end up being eliminated.
