metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. 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".

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.

CopyFromReg nodes for aliasing registers (AX and AL). This confuses the fast
register allocator.

Instead of CopyFromReg(AL), use ExtractSubReg(CopyFromReg(AX), sub_8bit).

introduced in r106343, but only showed up recently (with a particular compiler &
linker combination) because of the particular check, and because we have no
builtin checking for dereferencing the end of an array, which is truly
unfortunate.
