convention with a new call with a different calling convention.

ea9ca0236d simplify-libcalls: fold strncmp(x, y, 1) -> memcmp(x, y, 1) 
The memcmp will be optimized further and even the pathological case
'strstr(x, "x") == x' generates optimal code now.

551754c495 Revert 101465, it broke internal OpenGL testing. 
Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

4ec2258ffb 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
