Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.

For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:

      .globl l_objc_msgSend_fixup_alloc
      .weak_definition l_objc_msgSend_fixup_alloc
      .section __DATA, __objc_msgrefs, coalesced
      .align 3
l_objc_msgSend_fixup_alloc:
       .quad   _objc_msgSend_fixup
       .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

Currently only supported on Darwin platforms.

- Add AVX SSE2 Move doubleword and quadword instructions.
- Add encode bits for VEX_W

The encoding is the same as VMOV (from scalar to core register) except that
the operands are in different places.

a CPSR operand to them causes an assertion failure, so apparently these
instructions haven't been getting a lot of use.

If we want to make a copy (or estimate its cost), it is better to use the
smallest class as more efficient operations might be possible.
