hipe_x86: Minimise CFG<->linear conversions
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.
