Removed redundant helper functions for allocating Strong handles

Removed redundant helper functions for allocating Strong handles
https://bugs.webkit.org/show_bug.cgi?id=69218

Reviewed by Sam Weinig.

../JavaScriptCore:

* heap/Heap.h:
(JSC::Heap::handleHeap):
* runtime/JSGlobalData.h: Removed these helper functions, since they
just created indirection.

* heap/StrongInlines.h: Added. Broke out a header for inline functions
to resolve circular dependencies created by inlining. I'm told this is
the future for JavaScriptCore.

* GNUmakefile.list.am:
* JavaScriptCore.gypi:
* JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj:
* JavaScriptCore.xcodeproj/project.pbxproj: Go forth and build.

* API/JSCallbackObjectFunctions.h:
(JSC::::init):
* runtime/WeakGCMap.h:
(JSC::WeakGCMap::add):
(JSC::WeakGCMap::set):
* runtime/StructureTransitionTable.h:
(JSC::StructureTransitionTable::setSingleTransition):
* heap/Local.h:
(JSC::::Local):
* heap/Strong.h:
(JSC::::Strong):
(JSC::::set):
* heap/Weak.h:
(JSC::Weak::Weak):
(JSC::Weak::set): Allocate handles directly instead of going through a
chain of forwarding functions.

* bytecompiler/BytecodeGenerator.cpp:
* runtime/JSGlobalData.cpp:
* runtime/LiteralParser.cpp:
* runtime/RegExpCache.cpp: Updated for header changes.
