Better mangling for new-expressions. Also, although we can't mangle arbitrary initializer lists yet (we will need this), turn the crash into a controlled error.

Work-in-progress for lambda conversion-to-block operator.  Still need to implement the retain+autorelease outside of ARC, and there's a bug that causes the generated code to crash in ARC (which I think is unrelated to my code, although I'm not completely sure).

it can only bring pain when dealing with preprocessor abuse (see: boost).

RetainCountChecker: don't adjust the retain count when analyzing a ReturnStmt unless we are in the top-level call frame.  We can do more later, but this makes the checker self-consistent (and fixes a crash).

more harm than good.

Assume none of the ObjC messages defined in system headers free memory,
except for the ones containing 'freeWhenDone' selector. Currently, just
assume that the region escapes to the messages with 'freeWhenDone'
(ideally, we want to treat it as 'free()').

For now, always assume that regions escape when passed to C++ methods.

explicit conversion functions to initialize the argument to a
copy/move constructor that itself is the subject of direct
initialization. Since we don't have that much context in overload
resolution, we end up threading more flags :(.

  A defaulted default constructor for a class X is defined as deleted if [...]
    -  X is a union and all of its variant members are of const-qualified type.

A pedantic reading therefore says that

 union X { };

has a deleted default constructor, which is both silly and almost
certainly unintended. Pretend as if this this read

    - X is a union with one or more variant members, and all of its
      variant members are of const-qualified type.

agreed on IRC, any remaining issues are best dealt with as bugs.

We have no __has_feature check for this; please shout if you'd like one. This
feature seems too small to be worth its own release notes bullet (again, please
shout if you disagree).

  - Make sure that the block expression is instantiation-dependent if the
    block is in a dependent context
  - Make sure that the C++ 'this' expression gets captured even if we
  don't rebuild the AST node during template instantiation. This would
  also have manifested as a bug for lambdas.
