New Revision: 139953

URL: http://llvm.org/viewvc/llvm-project?rev=139953&view=rev
Log:
Add mayLoad attribute to AVX convert instructions, since non of them
are declared with load patterns. This fix the crash in PR10941. No testcases,
since a fold is triggered and then converted back to the register form
afterwards.
