2016-11-15hipe_rtl: unify branch and alubMagnus Lång
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').
