[AArch64] Fix miscompile of sdiv-by-power-of-2. When the constant divisor was larger than 32bits, then the optimized code generated for the AArch64 backend would emit the wrong code, because the shift was defined as a shift of a 32bit constant '(1<<Lg2(divisor))' and we would loose the upper 32bits. This fixes rdar://problem/18678801. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219934 91177308-0d34-0410-b5e6-96231b3b80d8
