Instead of using operator bool() for testing if a BindingKey is valid, use an explicit isValid() method.

the usage type of each declaration result, then compare those types to
the preferred type of the completion. This provides parity in the
priority calculation between the code-completion results produced
directly from Sema and those cached by ASTUnit. 

For the standard Cocoa.h (+ others) example, there's a penalty of 3-4
hundredeths of a second when caching the global results (for ~31,000
results), because we need an ASTContext-agnostic representation of
types for the comparison, and therefore we use... strings. Eventually,
we'd like to implement a more efficient ASTContext-agnostic encoding
of types.

type class, so that we can adjust priorities appropriately when the
preferred type for the context and the actual type of the completion
are similar.

This gets us one step closer to parity of the cached completion
results with the non-cached completion results.

- 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.

- 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.

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.

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.

Update CStringChecker to take advantage of the new metadata symbols and region change callback. Now does basic tracking of string length for general regions. Currently this is still only used for modeling strlen().

Add a callback for when region changes occur. Still somewhat of a work-in-progress, but working! Effect on clients: all changes to a store now go through GRState.
