Eli Friedman 71f5c2f158 Fix an issue with the IR sink pass found by inspection. (I'm not sure anyone is actually using this, but might as well fix it since I found the issue.)

Jakob Stoklund Olesen 5dc87d0f4d 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.

Jakob Stoklund Olesen 6357fa2f06 Prevent remat of partial register redefinitions. 
An instruction that redefines only part of a larger register can never
be rematerialized since the virtual register value depends on the old
value in other parts of the register.

This was fixed for the inline spiller in r138794.  This patch fixes the
problem for all register allocators, and includes a small test case.

Andrew Trick 832a6a1909 PreRA scheduler should avoid cloning compares. 
Added canClobberReachingPhysRegUse() to handle a particular pattern in
which a two-address instruction could be forced to interfere with
EFLAGS, causing a compare to be unnecessarilly cloned.

Thumb2 is a superset of Thumb1, so all of the encodings should still work.
