RFC: Removing the integrated REPL

Development Compiler
4

Hi,

I sometimes use integrated REPL explicitly as swift -frontend -repl because it works in a docker container launched without the --privileged option.
If integrated REPL is removed, it would be nice if LLDB REPL could be invoked in a docker container without the --privileged option.

FYI, how to try integrated REPL on macOS:

$ swift -frontend -repl -sdk $(xcrun -sdk macosx -show-sdk-path)
***  You are running Swift's integrated REPL,  ***
***  intended for compiler and stdlib          ***
***  development and testing purposes only.    ***
***  The full REPL is built as part of LLDB.   ***
***  Type ':help' for assistance.              ***
(swift) :help
Available commands:
  :quit - quit the interpreter (you can also use :exit or Control+D or exit(0))
  :autoindent (on|off) - turn on/off automatic indentation of bracketed lines
  :constraints debug (on|off) - turn on/off the debug output for the constraint-based type checker
  :dump_ir - dump the LLVM IR generated by the REPL
  :dump_decl <name> - dump the AST representation of the named declarations
  :dump_source - dump the user input (ignoring lines with errors)
  :print_decl <name> - print the AST representation of the named declarations
  :print_module <name> - print the decls in the given module, but not submodules
API documentation etc. will be here eventually.

Changed command line syntax from fish to zsh
