compiler: simplify live-info defined set semantics.
* stdlib/optimize.tl (basic-blocks local-liveness): Just
store the mask of defined registers into each live-info.
Do not propagate the defined mask from the next instruction
backwards. The way the defined mask is used in calc-liveness,
this makes no difference, and is simpler and faster.
