Fix a dagcombine optimization. The optimization attempts to optimize a bitcast of fneg to integers
by xoring the high-bit. This fails if the source operand is a vector because we need to negate each of the elements in the vector. Fix rdar://12281066 PR13813. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163802 91177308-0d34-0410-b5e6-96231b3b80d8
