Merge branch 'arm32'

Add initial 32-bit ARM support and additionally build out internal
breakpoint design to allow the use of single-step oriented breakpoints.

* arm32:
  Always prune step breakpoints when uninstalling from memory
  Update detect_breakpoint() to better handle single stepping
  Add architecture-specific single step support
  Add 32-bit ARM architecture params
