Log Message:
Add new flag to disable select optimizations for debugging (#27918)

Adds a new flag to disable select optimizations for debugging. The new
flag, --debug-safe-optmizations-only, will turn off a number of Chapel
optimizations that we have identified as hindering debugging.

Resolves Disable select optimization passes when `--debug`/`-g` is used · Issue #27615 · chapel-lang/chapel · GitHub

Other changes in this PR

  • Renamed -g/--debug to -g/--debug-symbols
  • Add a new flag, --debug, which implies -g and
    --debug-safe-optmizations-only
  • for a limited time, users will receive a warning when using this flag
    letting them now its doing more than previously
  • While adding this warning, I also cleaned up the warning for editions
    so they only get printed once
  • Cleanup and reorder docs/flags related to debugging and C code
    generation
  • paratest with/without gasnet
