BUG: mis-compilation of floating point literal patterns

[crusso]

Float point literal patterns are accepted by the type checker but not compiled correctly.

• executed in the interpreter
• non implemented in the compiler(s).

We should either rule them out or support them.

Repro:

actor Echo {

  // Say the given phase.
  public query func check(number : Float) : async { #Zero; #NotZero } {
    switch (number) {
      case (0) #Zero;
      case (_) #NotZero;
    };
  };
};

Call check(0.0) produces Canister called ic0.trap with message: TODO: compile_lit_pat
