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.

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=btver1.
