  1. Revert r363802, r363850, and r363856 "[TargetLowering] SimplifyDemandedBits..."

    This reverts the following patches.
    "[TargetLowering] SimplifyDemandedBits SIGN_EXTEND_VECTOR_INREG -> ANY/ZERO_EXTEND_VECTOR_INREG"
    "[TargetLowering] SimplifyDemandedBits ZERO_EXTEND_VECTOR_INREG -> ANY_EXTEND_VECTOR_INREG"
    "[TargetLowering] SimplifyDemandedBits - add ANY_EXTEND_VECTOR_INREG support"

    We can end up with an any_extend_vector_inreg with a 256 bit result type
    and a 128 bit result type. This is allowed by the ISD opcode, but the
    generic operation legalizer is only able to expand cases where the
    total vector width is the same.

    The X86 backend creates these mismatched cases for zext_vec_inreg/sext_vec_inreg.
    The SimplifyDemandedBits changes are allowing those nodes to become
    aext_vec_inreg. For the zext/sext cases, the X86 backend has Custom
    handling and never lets them get to the generic legalizer. We need to do the same
    for aext_vec_inreg. (detail/ViewSVN)

  6. [InstCombine][NFC] Add test to show missing fold for icmp ult/uge (shl %x, C2), C1.

    'shl' inequality test

      icmp ult/uge (shl %x, C2), C1 iff C1 is power of two

    can be simplified as 'and' equality test

      icmp eq/ne (and %x, (lshr -C1, C2)), 0.

  7. [InstCombine] Fold  icmp eq/ne (and %x, C), 0 iff (-C) is power of two -> %x u</u>= (-C)  earlier.

    To generate simplified IR, make sure fold
      (X & ~C) ==/!= 0 --> X u</u>= C+1

    is scheduled before fold
      ((X << Y) & C) == 0 -> (X & (C >> Y)) == 0.

  8. [llvm-objcopy][NFC] Refactor output target parsing

    Use an enum instead of string to hold the output file format in Config.InputFormat and Config.OutputFormat. It's essential to support other output file formats other than ELF.

  9. DataExtractor: use decodeSLEB128 to implement getSLEB128

    Should've been NFC, but turns out DataExtractor had better test coverage
    for decoding SLEB128 than the decodeSLEB128 did - revealing a couple of
    bugs (one in the error handling, another in sign extension). So fixed
    those to get the DataExtractor tests passing again. (detail/ViewSVN)
