Log:
  Pull in r262772 from upstream clang trunk (by Simon Pilgrim):

    [X86] AMD Bobcat CPU (btver1) doesn't support XSAVE

    btver1 is a SSSE3/SSE4a only CPU - it doesn't have AVX and doesn't
    support XSAVE.

    Differential Revision: http://reviews.llvm.org/D17682

  Pull in r262782 from upstream llvm trunk (by Simon Pilgrim):

    [X86] AMD Bobcat CPU (btver1) doesn't support XSAVE

    btver1 is a SSSE3/SSE4a only CPU - it doesn't have AVX and doesn't
    support XSAVE.

    Differential Revision: http://reviews.llvm.org/D17683

  This ensures clang does not emit AVX instructions for CPUTYPE=3Dbtver1.
