  Big refactor of breakpoints internal representation
  
  Big better
  
  At this point we now have to go and re-work the BrkArrays to consider internal breakpoints (generated in StgGen) and multi-threading. tomorrow.
  
  Continue refactor
  
  Lots of progress
  
  littel better
  
  compiler: make ModBreaks serializable
  
  Mais...
  
  BRK_FUN in rts
  
  Fixes
  
  Tweaks
  
  Checkpoint but segfaults in GC
  
  Start part 4....
  
  simpler
  
  allow allocating breakarrays outside of linking but in the linker env still
  
  disassemble
  
  tack todo
  
  The BreakArray construction at link time was originally done by Cheng.
