Simon Pilgrim 85bd9141ca [X86][MMX] Add support for MMX zero vector creation 
As mentioned on PR35869, (and came up recently on D41517) we don't create a MMX zero register via the PXOR but instead perform a spill to stack from a XMM zero register.

This patch adds support for direct MMX zero vector creation and should make it easier to add better constant vector creation in the future as well.
