compiler: propagate t-reg rename into end insn.
* stdlib/optimize.tl (basic-blocks rename): When we stop
the renaming due to an end instruction and the src
being a v-reg, we can still do the rename in that end
instruction itself. If the v-reg becomes invalid, that
doesn't happen until after the instruction.
