* origin/topic/vern/ZAM-remainder: (37 commits)
  fix race condition in btest output ordering
  whoops, forgot to canonicalize filenames in new btest
  extend btest to include a coercion overflow
  fixed a typo in a comment
  fixes for vector coercion overflows, typing, and holes
  factoring out logic to check for overflows during coercions
  test case for vector coercions, including holes
  low-level cleanups found by code review
  additional conversions of size() to empty() checks that were missed previously
  indentation nit
  flag loop that has slightly subtle logic
  use ## to start major sections
  a number of low-level tweaks from code review
  use std::find_if rather than explicit loop
  switch simple loops that don't need indices to being iterator-based
  use container empty() rather than size() where appropriate
  Baseline variants for "-a zam"
  new "-a ZAM" testing baseline alternative
  updates for usage issues: support for -uu, maybe/definitely distinctions
  enable reducer to track folding to enable constant propagation
