Speed up getABITypeSize by turning a i64 mul and div into an AND. This is speedup on any reasonable target, but particularly on 32-bit targets where this often turns into a libcall like udivdi3. We know that alignments are a power of two but the compiler doesn't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60688 91177308-0d34-0410-b5e6-96231b3b80d8
