Introduce new __predict_false(exp) and __predict_true(exp) keywords.
Their purpose is to give explicit hints to the compiler to judge
the likelyhood of a test to succeed or fail.  Not all architectures
have support for such optimizations, but for those who do, it can
give a nice performance improvement in hot loops.

Obviously, this should be used very rarely in very specific code.
