	branch and alub overlap in their use cases, but the backends rely on knowing that the result is unused in their lowering of branch. By extending alub so that the destination is optional, it can fully replace branch. This simplifies rtl by reducing code duplication and the number of instructions. Also, in the x86 and arm backends, we can now use 'test' and {'tst','mvn','teq'} to lower some alubs without destinations. This is particularly good for x86, as sequences such as 'is_boxed' type tests now get shorter (both from not needing a mov to copy the variable, but also from the fact that 'testb' encodes shorter than 'andq').

2014-03-07	Extend RTL API to support the LLVM backend	Yiannis Tsiouris
	Extend the 'rtl_var' definition to host liveness information needed for a simple liveness analysis performed by the LLVM backend. Also, uncomment some function definitions (mostly simple accessors) that are already there and are useful for the translation of RTL code to LLVM assembly. Finally, extend the RTL 'call' instruction with the 'normalcontinuation' field which is required for translating calls that are in the scope of an exception handler. This extra field is required in order to point to a new basic block which will hold the 'unwind label' of LLVM's invoke instruction. While the 'unwind label' is semantically equivalent with the 'failcontinuation', in LLVM this block must have a 'landingpad' instruction. The problem arises by the fact that an RTL 'continuation' block can also be accessible by other paths in the RTL CFG, and so cannot be marked as a landing pad. To overcome this issue we create a new block (the 'normalcontinuation') which is used as the 'unwind label' of LLVM's invoke instruction and which will eventually transfer control to the 'continuation' block.
