Hi Puyan,

The mir-canon-multi.mir test also appears to be non-deterministic.
Specifically the line "%namedVReg1353:vreg_64 = REG_SEQUENCE
%namedVReg1357, %subreg.sub0, %namedVReg1352, %subreg.sub1" always
appears, but its position isn't fixed and this can cause the test to
fail. It's hit green dragon in at least one case
(http://green.lab.llvm.org/green/job/clang-stage1-cmake-RA-incremental/47765/).

Cheers.

Tim.
