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.

The start block has no predecessors, so the following loop will not be executed.

bessaconstr: Move code, which is only needed for statistics, into the optionally compiled statistics part.

It is only used in one place for an assertion, where the start block can be retrieved locally.

It is sufficient to test, whether the zero bits equal the minimal value.
If they are all zero, the result is constant and this optimisation is unnecessary.

The walker does not invalidate the info and the user of the walker already assures it.

Infer it from block.

should be mostly bugfree by now and you can still use gdb for tracing
calls.

functions are already described in their headers with the declaration.
