Jean-Michel Gorius 2d66ce0e5e Revert "[CodeGen] Add support for multiple memory operands in MachineInstr::mayAlias"
This temporarily reverts commit 7019cea26dfef5882c96f278c32d0f9c49a5e516.

It seems that, for some targets, there are instructions with a lot of memory operands (probably more than would be expected). This causes a lot of buildbots to timeout and notify failed builds. While investigations are ongoing to find out why this happens, revert the changes.
