Richard Smith 3cb4c63073 DR974: Lambdas can have default arguments.

Richard Smith 10876ef571 Implement C++11 semantics for [[noreturn]] attribute. This required splitting
it apart from [[gnu::noreturn]] / __attribute__((noreturn)), since their
semantics are not equivalent (for instance, we treat [[gnu::noreturn]] as
affecting the function type, whereas [[noreturn]] does not).

Douglas Gregor adb376ec33 Implement C++ core issue 974, which permits default arguments for
lambda expressions. Because these issue was pulled back from Ready
status at the Kona meeting, we still emit an ExtWarn when using
default arguments for lambda expressions.

Douglas Gregor 1a22d2889b Lambdas have a deleted default constructor and a deleted copy
assignment operator, per C++ [expr.prim.lambda]p19. Make it so.

Douglas Gregor 12695101ec Implement the conversion to a function pointer for lambda expressions,
per C++ [expr.prim.lambda]p6.

Douglas Gregor a30a0bc1db Tests for C++ [expr.prim.lambda]p5. We already implement all of these
semantics.

Douglas Gregor 656bc62a73 Remove the "unsupported" error for lambda expressions. It's annoying,
and rapidly becoming untrue.

Douglas Gregor 8c50e7c5e3 Various interrelated cleanups for lambdas:
- Complete the lambda class when we finish the lambda expression
    (previously, it was left in the "being completed" state)
  - Actually return the LambdaExpr object and bind to the resulting
  temporary when needed.
  - Detect when cleanups are needed while capturing a variable into a
  lambda (e.g., due to default arguments in the copy constructor), and
  make sure those cleanups apply for the whole of the lambda
  expression.
