Add a simplified EmitJumpThroughFinally and use it in CGObjC in preparation of making it use the cleanup stack.

If people could beat on it and let me know if there are any new
semantics required by newer language standards or DRs or any little
details I goofed on, I'd be happy to fix any issues found.

the "system dirs win over user dirs" logic to framework and headermap
search locations as well as normal directories.  This means that
clang t.m -F/System/Library/Frameworks  will treat /System/Library/Frameworks
as a system directory not a user directory.  If you use -v, the difference is:

Before:
ignoring nonexistent directory "/usr/libdata/gcc41"
ignoring duplicate framework "/System/Library/Frameworks"
#include "..." search starts here:
#include <...> search starts here:

After:
ignoring nonexistent directory "/usr/libdata/gcc41"
ignoring duplicate directory "/System/Library/Frameworks"
  as it is a non-system directory that duplicates a system directory
#include "..." search starts here:
#include <...> search starts here:

Add support for emitting cleanup blocks. Make EmitCompoundStatement emit cleanup blocks if necessary

Add a simple RAII object, to be used for pushing a cleanup entry and make the insertion point be the cleanup block.

and start code gening break and continue in the presense of vlas.
