[Support] Remove llvm::alignOf now that all uses are gone.
Also clean up the legacy hacks for AlignedCharArray. I'm keeping LLVM_ALIGNAS alive for a bit longer because GCC 4.8.0 (which we still support apparently) shipped a buggy alignas(). All other supported compilers have a working alignas. llvm-svn: 284736
