Update X64 AsmFuncs.S to resolve a build failure using the
XCODE5 tool chain. This change updates AsmFuncs.S to match
AsmFuncs.asm and AsmFuncs.nasm.
The error generated in XCODE5 build is:
error: invalid instruction mnemonic 'movzxw'
movzxw 8(%rax), %rax
^~~~~~
The correct instruction is
movzwq 8(%rax), %rax
