MdeModulePkg/DebugSupportDxe: Fix XCODE5 build failure 

https://bugzilla.tianocore.org/show_bug.cgi?id=572

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
