9647f3d981 Avoid breaking vstd when reg_sequence is not used.

16d8f8bd91 I got tired of VISIBILITY_HIDDEN colliding with the gcc enum. Rename it
to LLVM_LIBRARY_VISIBILITY and introduce LLVM_GLOBAL_VISIBILITY, which is
the opposite, for future use by dragonegg.

ff7a562751 Implement a bunch more TargetSelectionDAGInfo infrastructure.
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.

07a6d9391c Use VSTMD / VLDMD for spills and reloads of Q registers instead of VSTMQ / VLDQ. The later are aliases which ought to be eliminated but we can't because they are used for storing and loading v2f64 values.
