Clear kill flags on all used registers when sinking instructions.
The test here was sinking the AND here to a lower BB:
%vreg7<def> = ANDWri %vreg8, 0; GPR32common:%vreg7,%vreg8
TBNZW %vreg8<kill>, 0, <BB#1>; GPR32common:%vreg8
which meant that vreg8 was read after it was killed.
This commit changes the code from clearing kill flags on the AND to clearing flags on all registers used by the AND.
