- We didn't allow for MSVC's extension of allowing certain constant

They allow various casts dereference and address-of operations.

Update StripDeadDebugInfo to use DebugInfoFinder so that it is no longer stale to the point of not working and more resilient to debug info changes.
The current version of StripDeadDebugInfo became stale and no longer actually

This patch updates it to use DebugInfoFinder and the modern DebugInfo classes as
much as possible to make it more redundent to such changes. Additionally, the
only place where that was avoided (the code where we replace the old sets with
the new), I call verify on the DIContextUnit implying that if the format changes
and my live set changes no longer make sense an assert will be hit. In order to
ensure that that occurs I have included a test case.
The actual stripping of the dead debug info follows the same strategy as was
used before in this class: find the live set and replace the old set in the
given compile unit (which may contain dead global variables/functions) with the
new live one.

Update to consumed analysis.
Patch by chris.wailes@gmail.com. The following functionality was added:
* The same functionality is now supported for both CXXOperatorCallExprs and CXXMemberCallExprs.
* Factored out some code in StmtVisitor.
* Removed variables from the state map when their destructors are encountered.
* Started adding documentation for the consumed analysis attributes.

DataFlowSanitizer: Prefix the name of each instrumented function with "dfs$".
DFSan changes the ABI of each function in the module. This makes it possible
for a function with the native ABI to be called with the instrumented ABI,
or vice versa, thus possibly invoking undefined behavior. A simple way
of statically detecting instances of this problem is to prepend the prefix
"dfs$" to the name of each instrumented-ABI function.
This will not catch every such problem; in particular function pointers passed
across the instrumented-native barrier cannot be used on the other side.
These problems could potentially be caught dynamically.

Add a separate llvm.global_ctors entry for linkonce_odr data initializers
Summary:
These typically come from static data members of class template
specializations. This accomplishes two things:
1. May expose GlobalOpt optimizations for Itanium C++ ABI code.
2. Works toward fixing double initialization in the Microsoft C++ ABI.

Test-time dependencies now live within test/clang-replace/Inputs which is more
