Check that the given Index expression is a valid array designator value.
This is essentially just a wrapper around VerifyIntegerConstantExpression that also checks for negative values and produces a reasonable diagnostic if there is a failure. Returns the index expression, possibly with an implicit cast added, on success. If everything went okay, Value will receive the value of the constant expression.

Converts the target of reference initialization so that it has the appropriate qualifiers and value kind.
In this case, 'x' is an 'int' lvalue, but it needs to be 'const int'.
In this case the reference is binding to a bitfield lvalue, which isn't valid. Perform a load to create a lifetime-extended temporary instead.

An egregious hack for compatibility with libstdc++-4.2: in <tr1/hashtable>, a function with a pointer return type contains a 'return false;' statement.
In C++11, 'false' is not a null pointer, so this breaks the build of any code using that header.
Work around this by treating 'return false;' as zero-initializing the result if it's used in a pointer-returning function in a system header.

When initializing a parameter, produce the value if it's marked attribute((ns_consumed)).
When initializing a return value, if the return type is a retainable type, then returns need to immediately retain the object. If an autorelease is required, it will be done at the last instant.
