Daco Harkes 2e1a56f264 [vm/msan] Fix MemCopyInstr instrumentation ...

The MemoryCopyInstr on x64 in MSAN mode when forward copying was
unpoisoning at the wrong pointer. The `rep mov` changes the
destination register.

Now we unpoison _before_ the `rep mov` if it's a forward copy, and
_after_ the `rep mov` for backwards copies. This way the destination
register contains the start of the memory in both cases.
