Jordy Rose 722f558f07 Model the effects of strcpy() and stpcpy() in CStringChecker. Other changes: 
- Fix memcpy() and friends to actually invalidate the destination buffer.
- Emit a different message for out-of-bounds buffer accesses if the buffer is being written to.
- When conjuring symbols, let ValueManager figure out the type.

Charles Davis 53c59df2f7 Implement support for member pointers under the Microsoft C++ ABI in the 
AST library.

This also adds infrastructure for supporting multiple C++ ABIs in the AST.

Jordy Rose df28e8ec41 - Allow making ElementRegions with complex offsets (expressions or symbols) for the purpose of bounds-checking. 
- Rewrite GRState::AssumeInBound to actually do that checking, and to use the normal constraint path.
- Remove ConstraintManager::AssumeInBound.
- Teach RegionStore and FlatStore to ignore those regions for now.

David Chisnall 589a494352 Pass some things to the linker that gcc passes. -r is the only one of these that I'm sure about, but the others seem to be listed on FreeBSD by gcc -dumpspecs, so I hope they're right. Apparently -r is also not passed on GNU/Linux (and should be), but I can't see where the toolchain definition for this platform live.

Douglas Gregor 3998219789 Extend the code-completion caching infrastructure to include global 
declarations (in addition to macros). Each kind of declaration maps to
a certain set of completion contexts, and the ASTUnit completion logic
introduces the completion strings for those declarations if the actual
code-completion occurs in one of the contexts where it matters. 

There are a few new code-completion-context kinds. Without these,
certain completions (e.g., after "using namespace") would need to
suppress all global completions, which would be unfortunate.

Note that we don't get the priorities right for global completions,
because we don't have enough type information. We'll need a way to
compare types in an ASTContext-agnostic way before this can be
implemented.

Argyrios Kyrtzidis 1b30d9c0f0 Commit improved version of 111026 & 111027. 
Unused warnings for functions:
-static functions
-functions in anonymous namespace
-class methods in anonymous namespace
-class method specializations in anonymous namespace
-function specializations in anonymous namespace

Unused warnings for variables:
-static variables
-variables in anonymous namespace
-static data members in anonymous namespace
-static data members specializations in anonymous namespace

Reveals lots of opportunities for dead code removal in llvm codebase that will
interest my esteemed colleagues.
