So maybe we can remove the mode check:
&& GET_MODE (testreg) == BLKmode)
The only problem I could think of is when we have a MEM within the PARALLEL,
then we should rather fall through to the code calling mark_used_regs
recursively in order to mark the regs holding the address as used. So perhaps
it is necessary to make sure that the PARALLEL only contains regs.
