The global type is final, so the next test bails out.

Accordingly remove repr_class from entities.

(This really shouldn't be allowed but until lower_calls is fixed this
should at least get complex working on sparc/arm)

In particular this ensures that the backend has segments for the PIC symbols and trampolines.

irgmod: Pass the new inputs to turn_into_tuple() instead of initialising them with Bad and setting them afterwards.

opt_inline: Move all start block placed nodes to the callee's start block, not just the constlike nodes.

Avoid negative switches.

Avoid negative switches.

The ipdom of each predecessor of the end block is the end block, so the subsequent loop does nothing.

The start block has no predecessors, so the subsequent loop will not be entered.

The next if tests for less than 2 predecessors, which the start block fulfills.

The start block does not end in a Jmp, which the next if checks.
