FoldConstantArithmetic() only knows how to deal with a few target independent ISD opcodes. Bail early if it sees a target-specific ISD node. These node do funny things with operand types which may break the assumptions of the code that follows, and there's no actual folding that can be done anyway. For example, non-constant 256 bit vector shifts on X86 have a shift-amount operand that's a 128-bit v4i32 vector regardless of what the first operand type is and that breaks the assumption that the operand types must match. rdar://16530923 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205937 91177308-0d34-0410-b5e6-96231b3b80d8
