[AVX512] Adding support for load truncate store of I1
store operation on a truncated memory (load) of vXi1 is poorly supported by LLVM and most of the time end with an assertion. This patch fixes this issue. Differential Revision: https://reviews.llvm.org/D39547 Change-Id: Ida5523dd09c1ad384acc0a27e9e59273d28cbdc9 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@320691 91177308-0d34-0410-b5e6-96231b3b80d8
