ArrayBoundCheckerV2: don't arbitrarily warn about indexing before the 0-index of a symbolic region.  In many cases that isn't really the base offset.

This patch adds modeling of strcmp() to the CString checker. Validates inputs are not NULL and are real C strings, then does the comparison and binds the proper return value. Unit tests included.

Fix bug in SimpleSValBuilder where '--' pointer arithmetic was treated like '++' pointer arithmetic.

RTTI is disabled. Similarly, don't suggest throw or try as code
completion results when C++ exceptions are disabled. Fixes

weak linkage.  Also, fix a problem where global weak variables
with non-trivial initializers were getting guard variables, or at
least were checking for them and then crashing.

for __unknown_anytype resolution to destructively modify the AST.  So that's
what it does now, which significantly simplifies some of the implementation.
Normal member calls work pretty cleanly now, and I added support for
propagating unknown-ness through &.

If there's an invoke destination, we should use invoke instead of call when calling the __cxa_bad_typeid function. Fixes PR7400.

Remove the CodeGenCXX/dyncast.cpp test; it isn't really super useful to match on huge chunks of LLVM output.

represents a dynamic cast where we know that the result is always null.

For example:

struct A {
  virtual ~A();
};
struct B final : A { };
struct C { };

bool f(B* b) {
  return dynamic_cast<C*>(b);
}

Strip off parens and no-op casts when deciding if an expr can be devirtualized. Fixes the second half of PR9660.

rewriting the literal when the value is integral. It is not uncommon to
see code written as:

  const int kBigNumber = 42e5;

Without any real awareness that this is no longer an ICE. The note helps
automate and ease the process of fixing code that violates the warning.

While I'm here, FileCheck-ize the ext-vector test, so we actually check
what it is generating.
