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

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

Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

Teach simplify libcall to transform __strcpy_chk to __memcpy_chk to enable optimizations down stream.

str[r]chr returns its pointer argument so we cannot mark it as nocapture. Thanks to Duncan for spotting my mistake.

move the tests to the new correct directory. Fix up tests that are now
optimized more than they were before by -instcombine.

can be used in more places.  Add an argument for the TargetData that
most of them need. Update for the getInt8PtrTy() change.  Should be
no functionality change.

Safely turn memset_chk etc. to non-chk variant if the known object size is >= memset / memcpy / memmove size.

SDISel.  This optimization was causing simplifylibcalls to 
introduce type-unsafe nastiness.  This is the first step, I'll be 
expanding the memcmp optimizations shortly, covering things that
we really really wouldn't want simplifylibcalls to do.
