to keep the node entries in scc_iterator up to date instead of dangling as
the SCC mutates.

This is a really terrible problem which was causing -g to affect codegen 
because it would permute the memory image of the compiler process.

Thanks to Dale for expertly hunting it down.

test, and should help support old versions of gold.

but now we have a much tidier interface.

suffixed "ul" to preserve the shift result.

Implemented printHex*ImmOperand() by copying from ARMAsmPrinter.cpp and added a
test case for DisassembleN1RegModImmFrm()/printHex64ImmOperand().

this patch removes the assert() from printAddrMode3OffsetOperand() and adds a test case.

Add a test case for this change which also tests the removal of assert() from
printAddrMode2OffsetOperand().

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
