e11cdf8cc8 TwoAddressInstructionPass doesn't really know how to merge live intervals when
lowering REG_SEQUENCE instructions.

Insert copies for REG_SEQUENCE sources not killed to avoid breaking later passes.

f2c9a96f3c Fix PR7156. If the sources of a REG_SEQUENCE are all IMPLICIT_DEF's. Replace it with an IMPLICIT_DEF rather than deleting it or else it would be left without a def.

3d98b996ff Turn on -neon-reg-sequence by default.
Using NEON load / store multiple instructions will no longer create gobs of vmov of D registers!
