Use a loop label in break expression
Break expression were using a raw lifetime value instead of a loop label
this behavior would have lead to some errors in ast validation.
gcc/rust/ChangeLog:
* ast/rust-expr.h (class BreakExpr): Change Lifetime to LoopLabel.
* hir/rust-ast-lower-expr.cc (ASTLoweringExpr::visit): Lower lifetime
inside the label instead.
* resolve/rust-ast-resolve-expr.cc (ResolveExpr::visit): Resolve the
inner lifetime.
