	Adds a new register allocator callback Target:branch_preds(Instr, Context) which, for a control flow instruction Instr, returns a list of tuples {Target, Probability} for each label name Target that Instr may branch to. Probability is a float between 0.0 and 1.0 and corresponds to the predicted probability that control flow branches to the corresponding target. The probabilities may sum to at most 1.0 (rounding errors aside). Note that a sum less than 1.0 is valid.

2016-08-30	hipe_x86: Minimise CFG<->linear conversions	Magnus Lång
	Most x86 passes were either linearise(pass(to_cfg(Code))) or trivially rewritable to process a CFG. This saves a great deal of time and memory churn when compiling large programs. Now, there will only ever be a single Linear->CFG conversion, just after lowering from RTL, and only ever a single CFG->Linear conversion, just before the finalise pass. Both of these now happen in hipe_x86_main.
