Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

callee is expected to be expanded to something else by codegen, so that
normal infinitely recursive calls are still transformed.

with a fix for self-hosting

rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

Do not mark no-return calls tail calls. It'll screw up special calls like longjmp and it doesn't make much sense for performance reason. If my logic is faulty, please let me know.

object is aligned as much as the load itself.

Fix a bunch of 80col violations that arose from the Create API change. Tweak makefile targets to find these better.

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.
