Implemented an implicit conversion from "noreturn" function types (and
...
pointers thereof) to their corresponding non-noreturn function
types. This conversion is considered an exact match for
overload-resolution purposes. Note that we are a little more strict
that GCC is, because we encode noreturn in the type system, but that's
a Good Thing (TM) because it does not allow us to pretend that
potentially-returning function pointers are non-returning function
pointers.
Fxies PR5620.

Add analysis support for blocks. This includes a few key changes:
...
- Refactor the MemRegion hierarchy to distinguish between different StackSpaceRegions for locals and parameters.
- VarRegions for "captured" variables now have the BlockDataRegion as their super region (except those passed by reference)
- Add transfer function support to GRExprEngine for BlockDeclRefExprs.
This change also supports analyzing blocks as an analysis entry point
(top-of-the-stack), which required pushing more context-sensitivity
around in the MemRegion hierarchy via the use of LocationContext
objects. Functionally almost everything is the same, except we track
LocationContexts in a few more areas and StackSpaceRegions now refer
to a StackFrameContext object. In the future we will need to modify
MemRegionManager to allow multiple StackSpaceRegions in flight at once
(for the analysis of multiple stack frames).
