New Revision: 101465

URL: http://llvm.org/viewvc/llvm-project?rev=101465&view=rev
Log:
reapply r101434
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
