Allow <undef> flags on def operands as well as uses.

The <undef> flag says that a MachineOperand doesn't read its register,
or doesn't depend on the previous value of its register.

A full register def never depends on the previous register value.  A
partial register def may depend on the previous value if it is intended
to update part of a register.

For example:

  %vreg10:dsub_0<def,undef> = COPY %vreg1
  %vreg10:dsub_1<def> = COPY %vreg2

The first copy instruction defines the full %vreg10 register with the
bits not covered by dsub_0 defined as <undef>.  It is not considered a
read of %vreg10.

The second copy modifies part of %vreg10 while preserving the rest.  It
has an implicit read of %vreg10.

This patch adds a MachineOperand::readsReg() method to determine if an
operand reads its register.

Previously, this was modelled by adding a full-register <imp-def>
operand to the instruction.  This approach makes it possible to
determine directly from a MachineOperand if it reads its register.  No
scanning of MI operands is required.

This patch implements the easiest form of register class inference:  For
every register class, and for every sub-register SubIdx, the subset of
registers in RC that have a SubIdx sub-register should also be a register
class.

This does create some new register classes for the targets in the tree:

ARM gets a new QQQQPR_with_ssub_0.  This class was omitted from the .td
file on purpose because it only has two registers.  InstrEmitter and
RegisterCoalescer have safeguards against selecting too small register
classes, so it is harmless.

PowerPC gets a G8RC_with_sub_32 class because LR is not a sub_32
sub-register of LR8.  I think that might be an omission?

X86 puts RIP in the GR64 class, and since that register doesn't have
8-bit sub-registers, we get:

  GR64_with_sub_8bit
  GR64_TC_with_sub_8bit
  GR64_NOREX_with_sub_8bit
  GR64_TC_with_sub_8bit_hi

The various CodeGen classes have already been fixed so adding new
register classes should not affect compile time.
