[Chapel Merge] Improve .gitignore

Improve .gitignore

With the goal of keeping the output of git status clean
after running a paratest on the tree, adjust .gitignore:

  • Update the paths to ignored files to match #16110 and #17070
  • Add a directory "hi", also to .cleanfiles, to match #15920
  • Add *.bc for llvm-enabled runs.

Going forward, we should populate .gitignore
in individual directories, rather than adding to the single
.gitignore in the root directory.
