Austin Clements 577c05ca1c cmd/compile: single pass over Blocks in Liveness.epilogue 
Currently Liveness.epilogue makes three passes over the Blocks, but
there's no need to do this. Combine them into a single pass. This
eliminates the need for blockEffects.lastbitmapindex, but, more
importantly, will let us incrementally compact the liveness bitmaps
and significantly reduce allocatons in Liveness.epilogue.

Passes toolstash -cmp.

Updates #24543.
