Permit remat of partial register defs when it is safe.

An instruction may define part of a register where the other bits are
undefined. In that case, it is safe to rematerialize the instruction.
For example:

  %vreg2:ssub_0<def> = VLDRS <cp#0>, 0, pred:14, pred:%noreg, %vreg2<imp-def>

The extra <imp-def> operand indicates that the instruction does not read
the other parts of the virtual register, so a remat is safe.

This patch simply allows multiple def operands for the virtual register.
It is MI->readsVirtualRegister() that determines if we depend on a
previous value so remat is impossible.
