Tobias Grosser 9a44b97913 Revert "CodeGeneration: Implement ceild/floord exactly as CLooG does"
I think I did not get the implementation right. As the current implementation
works well, we will just stick with it for now.

Sebastian Redl 86fab844bb Make CXXNewExpr contain only a single initialier, and not hold the used constructor itself.
Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities.

This breaks the static analysis of new expressions. I've filed PR12014 to track this.

Anna Zaks 95308d3798 [analyzer] Diagnostics: Ensure that the default end of diagnostic path
piece can always be generated.

The default end of diagnostic path piece was failing to generate on a
BlockEdge that was outgoing from a basic block without a terminator,
resulting in a very simple diagnostic being rendered (ex: no path
highlighting or custom visitors). Reuse another function, which is
essentially doing the same thing and correct it not to fail when a block
has no terminator.

We are not properly handling the memory regions that escape into struct

Bill Wendling b6f795eee6 Use the new method for specifying garbage collection metadata in the module.
The garbage collection metadata needs to be merged "intelligently", when two or
more modules are linked together, and not merely appended. (Appending creates a
section which is too large.) The module flags metadata method is the way to do
this.

Bill Wendling 7346277b6b Give a description of the Objective-C garbage collection module flags.
The rule governing the flags is this:

  no-gc + no-gc   = no-gc
  no-gc +    gc   = no-gc
  no-gc + gc-only = error
     gc +    gc   = gc
     gc + gc-only = gc-only
gc-only + gc-only = gc-only

Douglas Gregor d3b672c385 Implicitly define a lambda's conversion functions (to function
pointers and block pointers). We use dummy definitions to keep the
invariant that an implicit, used definition has a body; IR generation
will substitute the actual contents, since they can't be represented
as C++. 

For the block pointer case, compute the copy-initialization needed to
capture the lambda object in the block, which IR generation will need
later.
