Enhance understanding of VarRegions referenced by a block whose declarations are outside the current stack frame.  Fixes <rdar://problem/7462324>.

Improve linkage of RTTI data structures. Introduce CodeGenModule::GetAddrOfRTTI which figures out the right linkage of the RTTI information for the given type and whether it should be defined or not. I will migrate clients over to GetAddrOfRTTI in subsequent commits (with tests).

Fixes PR 5752.

is difficult because they're so terribly, terribly ambiguous.


We implement access declarations in terms of using declarations, which is
quite reasonable.  However, we should really persist the access/using
distinction in the AST and use the appropriate name in diagnostics.  This
isn't a priority, so I'll just file a PR and hope someone else does it. :)

When extending the lifetime of a temporary, make sure to emit a branch to the cleanup exit block. This fixes a broken module error in LLVMCConfigurationEmitter.cpp.

When an exception needs to be freed by calling __cxa_exception_free, make sure to stash away the exception pointer somewhere. 

This fixes an "Instruction does not dominate all uses!" verification error when compiling TableGen.

inconsistent situations if we do, and they are not important for PCH performance
(which currently only needs the stats to construct the initial FileManager
entries).
 - No test case, sorry, the machinations are too involved.

This occurs when, for example, the build makes a PCH file and has a header map
or a -I for a directory that does not yet exist. It is possible we will cache
the negative stat on that directory, and then in the build we will never find
header files inside that dir.

For PCH we don't need these stats anyway for performance, so this also makes PCH
files smaller w/ no loss. I hope to eventually eliminate the stat cache
entirely.

are a couple of O(n^2) operations in this, some analogous to the usual O(n^2)
redeclaration problem and some not.  In particular, retroactively removing
shadow declarations when they're hidden by later decls is pretty unfortunate.
I'm not yet convinced it's worse than the alternative, though.
