This speeds up local variable handling in DwarfDebug.

d361a77f14 Create a more targeted fix for not sinking instructions into a range where it
will conflict with another live range. The place which creates this scenerio is
the code in X86 that lowers a select instruction by splitting the MBBs. This
eliminates the need to check from the bottom up in an MBB for live pregs.

flag argument to addReg is not the same format as flags attached
to MachineOperand, although both have the same info.  I don't
think this actually mattered; the bootstrap failure did not
reproduce on the next run anyway.

1b2f94c621 Fix an exotic bug that only showed up in an internal test case.
SimpleRegisterCoalescing::JoinIntervals() uses CoalescerPair to determine if a
copy is coalescable, and in very rare cases it can return true where LHS is not
live - the coalescable copy can come from an alias of the physreg in LHS.

4ffd22d810 Add some missing checks for the case where the extract_subregs are
combined to an insert_subreg, i.e., where the destination register is larger
than the source.  We need to check that the subregs can be composed for that
case in a symmetrical way to the case when the destination is smaller.

75ac4d9c2d Avoid processing early clobbers twice in RegAllocFast.
Early clobbers defining a virtual register were first alocated to a physreg and
then processed as a physreg EC, spilling the virtreg.

This fixes PR7382.

40d07bbebb 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.

The CoalescerPair class will replace a lot of the spaghetti logic in JoinCopy
later.

852a7e362e 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.

4b559f070a The form of BuildMI used for TAILJMPr was changing the register
