Add a simplified EmitJumpThroughFinally and use it in CGObjC in preparation of making it use the cleanup stack.

If people could beat on it and let me know if there are any new
semantics required by newer language standards or DRs or any little
details I goofed on, I'd be happy to fix any issues found.

Add support for emitting cleanup blocks. Make EmitCompoundStatement emit cleanup blocks if necessary

Add a simple RAII object, to be used for pushing a cleanup entry and make the insertion point be the cleanup block.

and start code gening break and continue in the presense of vlas.

   EmitFunction{Epi,Pro}log.

 - Lift CGFunctionInfo creation up to callers of EmitCall.

 - Move isVariadic bit out of CGFunctionInfo, take as argument to
   GetFunctionType instead.

Emit the size even if the declared type is a variably modified type. This lets us handle

Store the size of the EH stack inside each BreakContinue struct so we know when a break/continue won't cross a try block.
