This implements the 'landingpad' instruction. It's used to indicate that a basic block is a landing pad. There are several restrictions on its use (see LangRef.html for more detail). These restrictions allow the exception handling code to gather the information it needs in a much more sane way. This patch has the definition, implementation, C interface, parsing, and bitcode support in it. llvm-svn: 137501
