MC: Improve the .fill directive's compatibility with GAS Per the GAS documentation, .fill should permit pattern widths that aren't a power of two. While I was in the neighborhood, I added some sanity checking. This change was motivated by a use of this construct in the Linux Kernel. llvm-svn: 200606

Basic .s parsing for .asci[iz], .fill, .space, {.byte, .short, ... } - Includes some DG tests in test/MC/AsmParser, which are rather primitive since we don't have a -verify mode yet. llvm-svn: 74139
