Fix an obvious problem with an alignment computation. AsmPrinter actually does
the max itself, so it is not easy to write a test case for this, but I added a test case that would fail if the code in AsmPrinter were removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129432 91177308-0d34-0410-b5e6-96231b3b80d8
