Teach ARMLoadStoreOptimizer to remove kill flags from merged instructions as well.
This is necessary to avoid a crash in certain tangled situations where a kill
flag is first correctly moved to a merged instruction, and then needs to be
moved again:
STR %R0, a...
STR %R0<kill>, b...
First becomes:
STR %R0, b...
STM a, %R0<kill>, ...
and then:
STM a, %R0, ...
STM b, %R0<kill>, ...
We can now remove the kill flag from the merged STM when needed. 8960050.
