1. rust: Desugar IfLet* into MatchExpr …

   Replace the "regular" AST->HIR lowering for IfLet* with a desugaring
   into a MatchExpr.
   
   Desugar a simple if let:
   
      if let Some(y) = some_value {
        bar();
      }
   
   into:
   
      match some_value {
        Some(y) => {bar();},
        _ => ()
      }
   
   Same applies for IfLetExprConseqElse (if let with an else block).
   
   Desugar:
   
      if let Some(y) = some_value {
        bar();
      } else {
        baz();
      }
   
   into:
   
      match some_value {
        Some(y) => {bar();},
        _ => {baz();}
      }
   
   Fixes #1177
