2017-03-16hipe: Add pseudo_spill_f?move instructionsMagnus Lång
These pseudo instructions are added to all backends and allow spill slot to spill slot move coalescing in a clean way. They have regular move semantics, but contain an additional scratch register to be used if both source and destination are spilled, and can not be move coalesced. Additionally, a register allocator callback Target:is_spill_move(Instr, Context) is added which allows the spill slot allocators to check for these instructions and try to coalesce the spill slots the two temporaries are allocated to.

2016-08-30hipe_x86: Minimise CFG<->linear conversionsMagnus 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.
