[AsmPrinter] Make isRepeatedByteSequence smarter about odd integer types - zext the value to alloc size first, then check if the value repeats with zero padding included. If so we can still emit a .space - Do the checking with APInt.isSplat(8), which handles non-pow2 types - Also handle large constants (bit width > 64) - In a ConstantArray all elements have the same type, so it's sufficient to check the first constant recursively and then just compare if all following constants are the same by pointer compare llvm-svn: 239977
