print("Hello, 64-bit jitted world!");
Get hello-world working through the JIT, on x86-64.

• assembler/X86Assembler.h:

Fix encoding of opcode + RegisterID format instructions for 64-bit.

• interpreter/Interpreter.cpp:
• interpreter/Interpreter.h:

Make VoidPtrPair actually be a pair of void*s.
(Possibly should make this change for 32-bit Mac platforms, too - but won't change 32-bit behaviour in this patch).

• jit/JIT.cpp:
• jit/JIT.h:

Provide names for the timeoutCheckRegister & callFrameRegister on x86-64,
force x86-64 ctiTrampoline arguments onto the stack,
implement the asm trampolines for x86-64,
implement the restoreArgumentReference methods for x86-64 calling conventions.

• jit/JITCall.cpp:
• jit/JITInlineMethods.h:
• wtf/Platform.h:

Add switch settings to ENABLE(JIT), on PLATFORM(X86_64) (currently still disabled).
