Add a separate unrolling threshold when the current function is being optimized for size.

The threshold value of 50 is arbitrary, and I chose it simply by analogy to the inlining thresholds, where
the baseline unrolling threshold is slightly smaller than the baseline inlining threshold. This could
undoubtedly use some tuning.

Don't add <imp-def> operands during register rewriting.
...
LiveIntervals already adds <imp-def> operands for super-registers when a subreg
def defines the whole register. Thus, it is not necessary to do it again when
rewriting.
In fact, the super-register imp-defs caused miscompilations because the late
scheduler couldn't see that the super-register was read.
We still add super-reg <imp-use,kill> operands when rewriting virtuals to
physicals.

register must be one of the destination registers for the load. Otherwise,

desired (otherwise, we'd have a t2LDM_UPD instead).
