Prevent obscure and incorrect tail-call optimization. In this instance we are generating the tail-call during legalizeDAG. The 2nd floor call can't be a tail call because it clobbers %xmm1, which is defined by the first floor call. The first floor call can't be a tail-call because it's not in the tail position. The only reasonable way I could think to fix this in a target-independent manner was to check for glue logic on the copy reg. rdar://10930395 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151877 91177308-0d34-0410-b5e6-96231b3b80d8

Enable sibling call optimization of libcalls which are expanded during legalization time. Since at legalization time there is no mapping from SDNode back to the corresponding LLVM instruction and the return SDNode is target specific, this requires a target hook to check for eligibility. Only x86 and ARM support this form of sibcall optimization right now. rdar://8707777 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120501 91177308-0d34-0410-b5e6-96231b3b80d8
