[llvm-dev] Detect exception throwing in basic blocks

[Reid Kleckner via llvm-dev]

In LLVM IR, you would see an `invoke` instruction that calls the
appropriate C++ runtime function to set up a C++ exception. It would be
__cxa_throw or CxxThrowException on Windows.

Since only function calls can throw, this is not a property of the basic
block, but a property of individual call instructions.
