Speed up function.apply(..., arguments)
​https://bugs.webkit.org/show_bug.cgi?id=46207

Add code to do argument copying inline in the case
where we're using Function.apply to forward our arguments
directly.

• jit/JIT.cpp: (JSC::JIT::privateCompileSlowCases):

Splitted op_load_varargs into fast and slow paths, so add the call
to the slow path generator.

• jit/JIT.h:
• jit/JITCall32_64.cpp: Remove 32bit specific emit_op_load_varargs as the logic is the same for all value representations
• jit/JITOpcodes.cpp: (JSC::JIT::emit_op_load_varargs): Copy arguments inline (JSC::JIT::emitSlow_op_load_varargs):
