Avoid CFG reachability check after SCCP
...
SCCP eliminates unreachable BBs before the CFG constraction.
So ir_build_cfg() doesn't need to perforem reachability chececk if it
runs after SCCP, otherwise it starts call ir_remove_unreachable_blocks() if necessary.
User code dont have to call ir_remove_unreachable_blocks() anymore.

Create a sparate pass to remove unreachableble CFG blocks.
...
SCCP pass removes unreachable blocks before CFG construction.
In case of -O0 or -O1 pipeline (without SCCP) it's simpler and faster
to unlink unreachable CFG blocks once, then check for reachability
in almost any compilation pass.
-O2 pipeline (with SCCP) don't need this pass.
