  Log Message:
  -----------
  [X86] Add ISD::FREEZE and ISD::AssertAlign to the list of opcodes that don't guarantee upper 32 bits are zero.

The freeze issue was reported here
https://llvm.discourse.group/t/bug-or-feature-freeze-instruction/3639

I don't have a test for AssertAlign. I just noticed it was missing
and assume it should be similar to the other two Asserts.
