Austin Clements bf9ad7080d runtime: remove another TODO 
I experimented with having the compiler spill the two registers that
are clobbered by the write barrier fast path, but it slightly slows
down compilebench, which is a good write barrier benchmark:

name       old time/op     new time/op     delta
Template       175ms ± 0%      176ms ± 1%    ~           (p=0.393 n=10+10)

Since this didn't pan out, remove the TODO.
