  -----------
  [flang] add a pass to move array temporaries to the stack

This pass implements the `-fstack-arrays` flag. See the RFC in
`flang/docs/fstack-arrays.md` for more information.

  Log Message:
  -----------
  [flang] add -fstack-arrays flag

The implementation of -fstack-arrays was added in
https://reviews.llvm.org/D140415

The new macro BoolOptionWithoutMarshalling in Options.td avoids
generating code to store the flags in clang data structures. For
example, writing something like

  defm stack_arrays : BoolOption<"f", "stack-arrays",
                                 CodeGenOpts<"StackArrays">, [...]

Would generate code referring to `clang::CodeGenOpts::StackArrays`, which
does not exist.
