Elena Demikhovsky	e5bbca6ae2	Optimized loading (zextload) of i1 value from memory. This patch is a partial revert of https://llvm.org/svn/llvm-project/llvm/trunk@237793. Extra "and" causes performance degradation. We assume that i1 is stored in zero-extended form. And store operation is responsible for zeroing upper bits.
