*	Prevent obscure and incorrect tail-call optimization.	Chad Rosier	2012-03-02	1	-0/+29
\| \| \| \| \| \| \| \| \| \| \| \| \|	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

	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
