Add CoalescerPair helper class.

Given a copy instruction, CoalescerPair can determine which registers to
coalesce in order to eliminate the copy. It deals with all the subreg fun to
determine a tuple (DstReg, SrcReg, SubIdx) such that:

- SrcReg is a virtual register that will disappear after coalescing.
- DstReg is a virtual or physical register whose live range will be extended.
- SubIdx is 0 when DstReg is a physical register.
- SrcReg can be joined with DstReg:SubIdx.

CoalescerPair::isCoalescable() determines if another copy instruction is
compatible with the same tuple. This fixes some NEON miscompilations where
shuffles are getting coalesced as if they were copies.

Generalize the pre-coalescing of extract_subregs feeding reg_sequences,
replacing the overly conservative checks that I had introduced recently to
deal with correctness issues.  This makes a pretty noticable difference
in our testcases where reg_sequences are used.  I've updated one test to
check that we no longer emit the unnecessary subreg moves.

The form of BuildMI used for TAILJMPr was changing the register

it's wrong.
