Allow overlaps between virtreg and physreg live ranges.
The RegisterCoalescer understands overlapping live ranges where one
register is defined as a copy of the other. With this change, register
allocators using LiveRegMatrix can do the same, at least for copies
between physical and virtual registers.
When a physreg is defined by a copy from a virtreg, allow those live
ranges to overlap:
%CL<def> = COPY %vreg11:sub_8bit; GR32_ABCD:%vreg11
%vreg13<def,tied1> = SAR32rCL %vreg13<tied0>, %CL<imp-use,kill>
We can assign %vreg11 to %ECX, overlapping the live range of %CL.

Remove unused private fields found by clang's new -Wunused-private-field.
There are some that I didn't remove this round because they looked like
obvious stubs. There are dead variables in gtest too, they should be
fixed upstream.

Extend the CoalescerPair interface to handle symmetric sub-register copies.
Now both SrcReg and DstReg can be sub-registers of the final coalesced
register.
CoalescerPair::setRegisters still rejects such copies because
RegisterCoalescer doesn't yet handle them.

Move the RegisterCoalescer private to its implementation file.
RegisterCoalescer.h still has the CoalescerPair class interface.

Eliminate copies of undefined values during coalescing.
These copies would coalesce easily, but the resulting value would be
defined by a deleted instruction. Now we also remove the undefined value
number from the destination register.
This fixes PR10503.
