Fix a codegen fault in which log2 or exp2 could be dead-code eliminated even though they could have sideeffects. Only allow log2/exp2 to be converted to an intrinsic if they are declared "readnone". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151807 91177308-0d34-0410-b5e6-96231b3b80d8
