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);

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.

This fixes 1 error when parsing MSVC 2010 header files with clang.

when building with Visual Studio. `clang.dll' and `clang.exe' would
have the same `clang.ilk' and `clang.pdb'. On a serial build those
files would be overwritten as clang.exe/clang.dll are created. On a
parallel build there is a risk of both files being written at the same
time. On that case VS fails.

* Add a "landing pad" attribute to the BasicBlock.
* Modify the bitcode reader and writer to handle said attribute.

Later: The verifier will ensure that the landing pad attribute is used in the
appropriate manner. I.e., not applied to the entry block, and applied only to
basic blocks that are branched to via a `dispatch' instruction.

(This is a work-in-progress.)

LLVMCC_EMITIR_FLAG is already either -emit-llvm or -fplugin-arg-dragonegg-emit-ir, so don't add an extra leading -.  Clang doesn't accept --emit-llvm.
